## How to Find Linear Combination?

A linear equation of the form Ax + By = C. Here, x and y are variables, and A, B, and C are constants. A Linear combination calculator is used to solve a system of equations using the linear combination method also known as the elimination method.

To solve the variables of the given equations, let's see an example to understand briefly.

**Solved Example:**

Solve the given linear combination equations 2x + y = 7 and x + y = 5

**Solution:**

2x + y = 7 ------> (1)

x + y = 5 -------> (2)

To eliminate 'y', subtract (1) - (2),

2x + y - x - y = 7 - 5

x = 2

Substitute x = 2 in equation(1),

2(2) + y = 7

4 + y = 7

y = 3

Therefore, x = 2, y = 3

Similarly, you can try the calculator to solve the linear combination equations for:

- 7x + 8y = 17 and x - 16y = 4
- 11x - 17y = -18 and 12x - 15y = 8
