How to use the substitution method?
the problem is x=y+32x-y=5How to solve this equation in substitution method.
x = y + 32x - y = 5then-y = -x + 32x - 5 = ytheny = x - 32x - 5 = ybecause y is the same in both equations,x - 3 = 2x - 5x = 2then choose either equationx = y + 3(2) = y + 32 - 3 = y + 3 - 3y = -1
2(y+3)-y=5.find y and plug in for the first equation to find x.
You put (y+3) in place of the x 2(y+3)-y=52y+6-y+= 5y+6=5y=-1
