You have to set the expressions equal to each other since they're vertical angles, so its 4x+7=5(x-4) then you get 4x+7=5x-20 you then subtract 4x to get 7=x-20 then after add 20 on both sides to get 27=x.

Answer:

b= -8

Step-by-step explanation:

we have: 3y +12 = 6x <=> y + 4 = 2x <=> y= 2x - 4

=> 2y=4x + b

<=> 2(2x-4) = 4x +b

<=> 4x - 8= 4x +b

<=> b = -8
