Question 400680: 8x+3y=-37
x=3-8y
Answer by sofiyac(983)   (Show Source):
You can put this solution on YOUR website! 8x+3y=-37
x=3-8y
Since the second equation is already solved for x, we can plug in 3-8y instead of x in the first equation. So we get
8(3-8y)+3y=-37 now you simplify
24-64y+3y=-37
24-61y=-37 subtract 24 from each side
24-24-61y=-37-24
-61y=-61 divide each side by -61
-61y/-61=-61/-61
y=1
Then you go back to the second equation and plug 1 instead of y, so you get
x=3-8*1
x=3-8
x=-5
So the solution is (-5,1)
