This linear combinations calculator is a great source for solving linear equations without doing any manual calculations on a platform without going to any teacher.

## What is a Linear Combination?

Linear combination is a process that is used in algebra to **evaluate the value** of unknown variables that are present in linear system equations. You can use this method to find one, two, or even three unknown variable values.

To get the solution of variables x, y, and z from the linear equation you can use the substitution method, elimination method, cross multiplication method, and graphing linear equation method.

### Linear Equations are:

The linear equation is the equation that has **order and degree one**, and you can add different numbers of variables. Only two variables are involved in the given equation: x and y. Whereas a, b, d, and e are coefficients of x and y, and c and f are constants,

$$ ax + by \;=\; c $$

$$ dx + ey \;=\; f $$

## Working of Linear Combination of Matrices Calculator:

Linear combination of matrix calculator use a simple and easy way to **solve linear systems** of equations involving finding the values of variables that satisfy the given equations simultaneously.

There are primarily two common methods to solve such systems: substitution and elimination. Here's how each method works:

**Substitution Method:**

To understand how the **substitution method** works to simplify the linear equation, suppose an example.

$$ \biggr[ \begin{matrix} 2x + 3y \;=\; 10 \\ x - y \;=\; 1 \\ \end{matrix} $$

**Step 1**: First, choose one of the equations and solve it for one variable. This means isolating one variable on one side of the equation to find the other variable value. Let's choose equation 2 because it is simplest than the first equation x−y=1, solve for x

**Step 2**: Separate the term x from the above equation that you choose as

$$ x - y \;=\; 1,\; x \;=\; 1 + y $$

**Step 3**: Now substitute x=y+1 into the first equation 2x+3y=10 and solve it to get the value of variable y.

$$ 2(y + 1) + 3y \;=\; 10 $$

$$ 2y + 2 + 3y \;=\; 10 $$

$$ 5y + 2 \;=\; 10 $$

$$ 5y \;=\; 10 - 2 $$

Divided by 5 on both sides to find the value of y which is y=8/5.

$$ 5y \;=\; 8 $$

**Step 4:** Substitute y=8/5 into the above equation to get the values of the x variable.

$$ x \;=\; y + 1 $$

$$ x \;=\; \frac{8}{5} + 1 $$

$$ x \;=\; \frac{13}{5} $$

**Step 5**: Substitute the values of x and y into one of the original equations to ensure they satisfy both equations simultaneously.

$$ 2x + 3y \;=\; 10 $$

$$ 2(\frac{13}{5})+3(\frac{8}{5}) \;=\; 10 $$

$$ \frac{26}{5} + \frac{24}{5} \;=\; 10 $$

$$ \frac{50}{5} \;=\; 10 $$

$$ 10 \;=\; 10 $$

Hence it satisfies the given equation so our values of x and y are true.

**Elimination Method:**

Let's suppose two **linear equations** to see how the elimination method work in the evaluation of variable x and y values.

$$ \biggr[ \begin{matrix} 2x & + & 3y & = & 10 \\ x & - & y & = & 1 \\ \end{matrix} $$

**Step 1**: Arrange the equations such that the coefficients of one of the variables in both equations are equal or opposite. This is achieved by multiplying one or both equations by suitable constants.**Example**:

$$ 2x + 3y \;=\; 10,\; x - y \;=\; 1 $$

Multiply the second equation by 2 to make the x variable in both equations.

$$ 2(x - y \;=\; 1) $$

$$ 2x - 2y \;=\; 2 $$

**Step 2**: Subtract both equations to eliminate one of the variables.

$$ \begin{matrix} 2x & + & 3y & = & 10 \\ \pm 2x & \mp & 2y & = & \pm 2 \\ \hline \\ 0x & + & 5y & = & 8 \\ \end{matrix} $$

$$ y \;=\; \frac{8}{5} $$

**Step 3**: To solve the equation for the remaining variable, substitute y value in one of the original values.

$$ 2x + 3y \;=\; 10\; put y \;=\; \frac{8}{5} $$

$$ 2x + 3(\frac{8}{5}) \;=\; 10 $$

$$ 2x + \frac{24}{5} \;=\; 10 $$

$$ 2x \;=\; 10 - \frac{24}{5} $$

$$ 2x \;=\; 50 - \frac{24}{5} $$

$$ x \;=\; \frac{26}{5 \times 2} $$

$$ x \;=\; \frac{13}{5} $$

**Step 4**: To verify the solution, put the values x and y in one of the original equations. If it satisfies then your values are correct.

$$ x - y \;=\; 1,\; x \;=\; \frac{13}{5},\; y \;=\; \frac{8}{5} $$

$$ (\frac{13}{5}) - (\frac{8}{5}) \;=\; 1 $$

$$ \frac{13}{5} - \frac{8}{5} \;=\; 1 $$

$$ 13 - \frac{8}{5} \;=\; 1 $$

$$ \frac{5}{5} \;=\; 1 $$

$$ 1 \;=\; 1 $$

Both methods are effective for solving systems of linear equations, depending on your preference or the specific structure of the equations.
