What is the Solution of Simultaneous Equations?

The solution is the pair of values of x and y that is true for both equations.

Given the simultaneous equations,

5x + y = -5

5x – 3y = 11

Subtract

4y = -16

y = -4

Substitute y = -4 into equation 1.

5x + (-4) = -5

5x - 4 = -5

5x = -5 + 4

5x = -1

x = -1/5
