Question

Solve the system of equations by the addition method.

{2x - 3y = 3
{- 3x + 2y = -2

Answer 1

2x - 3y = 3

- 3x + 2y = -2

so we have to make it so one of the variables matches

equation one times -3

-6x+9y=-9

equation two by 2

-6x+4y=-4

now lets subtract equation 2 by equation one

5y=-5

y=-1

now lets plug in

2x-3=3

+3

2x=6

x=3

the answer is (3,-1)
