Question 951188: In a rectangle, one side equals 6y-6 and its opposite side equals 2x+20. The other side equals 3x+21 and its opposite side equals 6y. Find x and y. Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! 6y=3x+21
6y=3(x+7)
2y=x+7
y=(x+7)/2
x=2y-7
.
2x+20=6y-6
2x=6y-26
x=3y-13
=3((x+7)/2)-13
=((3x+21)/2)-13
3x/2 - 5/2 = x
3x/2 -x = 5/2
3x-2x=5
5x=5
x=5
2x=6y-26
10=6y-26
6y=36
y=6
