Question 495607: I am trying to find the x and y of the following linear equation systems
2x + Y = -6
3x + Y = -10 Answer by IFY(62) (Show Source):
You can put this solution on YOUR website!
2x + y = -6 ----- equation 1
3x + y = -10 ----equation 2
first of all subtract equation 1 from equation 2
(2x - 3x)+ (y -y) = (-6 - -10)
-x + 0 = 4
-x = 4
x = -4
substitute x = -4 into equation 1
2x + y = -6
2(-4)+ y = -6
-8 + y = -6
y = -6 + 8
y = 2
