## How to Find Simultaneous Equations Calculator?

A linear equation of the form Ax + By = C. Here, x and y are variables, and A, B, and C are constants.

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

**Solved Example:**

Solve the given simultaneous equation 2x + y = 7 and x + y = 5

**Solution:**

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

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

From (2), x = 5 - y ------> (3)

Substitute (3) in (1),

2(5 - y) + y = 7

10 - 2y + y = 7

10 - y = 7

y = 3 ------> (4)

Substitute (4) in (2),

x + 3 = 5

x = 2

Therefore, x = 2, y = 3

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

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