Question

Which ordered pair is the solution to this system of equations? Use the elimination method.

3x+3y=15 3 x + 3 y = 15

-2x+3y=-5

Answer 1

(4,1)

3 x + 3 y = 15 - (-2 x + 3 y = -5)

3x + 3y = 15

2x - 3y = 5 +

____________

5x = 20

x = 4

(3*4) + 3y = 15

12 + 3y = 15

3y = 15 -12

3y = 3

y = 1

Answer 2

x=5

y=5

I think sorry if it didn't help ;)
