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
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?
