Math help please

1. Solve for x.

4(x - b) = x

b = 4/3x
b = 3/4x
x = 4/3b
x = 3/4b

2. Solve for y, then find the value of y when given x = 2.

6x = 7 - 4y

-12
7/4
19/4
24

I need help solving these. Can you please explain how to solve these problems?

  1. #1
    4(x-b) = x
    4x-4b = x
    3x = 4b
    x = 4/3 b

    #2
    6x = 7-4y
    4y = 7-6x
    y = (7-6x)/4

    y(2) = (7-6*2)/4
    = (7-12)/4
    = -5/4
    Hmmm. Typo? -6x = 7-4y?
