we solve for x and we get and substitute and we get
then the so y=2 and then x=1-4=-3

SOLVING SYSTEMS by SUBSTITUTION
Solve each system by substitution. check your answer.
2x+3y=0
x+2y=-1
2x + 3y = 0 ------ eq (i)
x + 2y = - 1 ------ x = - 1 - 2y
2(- 1 - 2y) + 3y = 0 ------ Substituting - 1 - 2y for x in eq (i)
- 2 - 4y + 3y = 0
- y = 2
y = , or - 2
2x + 3(- 2) = 0 ------ Substituting - 2 for y in eq (i)
2x - 6 = 0
2x = 6
x = , or 3
Solution set: (,)
I'll leave the check up to you!!!
