To use the elimination method, we either subtract or add the two equations to eliminate a variable. A variable is eliminated if it has a coefficient of 0.
For this problem, we can add the two equations to eliminate y, since 2+(-2)=0
(5x+2y=-3)
+(4x-2y=-6)
9x+0y=-9
9x=-9
x=-1 Divide both sides by 9 to isolate the x.
To solve for y, substitute x into any of the original equations and solve for y.
5(-1)+2y=-3
-5+2y=-3
2y=2 Add 5 to both sides
y=1 Divide both sides by 2
Thus your answer is (-1,1)
