If angle 2 = 7x + 7, angle 3 = 5y, and angle 4 = 140, find the values of x and y.

I'm not to sure but this is what I got

1.   2=7x+7

-7      -7

-5/7= 7x/7             What you do to one side you always do to the other.

x = -5/7

2.   3/5 = 5y/5

y = 3/5

Hope it helped! : )

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
