You can solve simultaneous equations by adding or subtracting the two equations in order to end up with an equation with only one unknown value.

Solve the following: 1) 5x + 3y = 24 y = 2x + -14 x = y = 2) 2x + 3y = -28 y = 1x + -6 x = y = 3) 2x + 5y = 26 y = 3x + -22 x = y = 4) 6x + 6y = 12

In this method, we substitute one variable from one equation into the other. The steps involved are: 1. Using either of the equations, express one variable ...
