Please, look at how does your problem write down in the book:
in the first way %2812%2Bx%29%2F-4=%285x-7%29%2F3%2B2
or in the second way 12%2Bx%2F-4=5x-7%2F3%2B2
.
The first
%2812%2Bx%29%2F-4=%285x-7%29%2F3%2B2
-%283%2A%2812%2Bx%29%2F12%29=%284%2A%285x-7%29%29%2F12%2B%282%2A12%29%2F12 Multiply all equation at 12
-3%2A12-3%2Ax=4%2A5x-4%2A7%2B24
-3x-20x=-28%2B24%2B36
-23x=32
x=32%2F%28-23%29
x=-32%2F23
x=-1 9/23
.
The second
12%2Bx%2F-4=5x-7%2F3%2B2
-x%2F4-5x=-7%2F3%2B2-12
-x%2F4-%284%2A5x%29%2F4=-7%2F3-10
%28-x-20x%29%2F4=-7%2F3-%283%2A10%29%2F3
%28-21x%29%2F4=%28-7-30%29%2F3
-%2821x%29%2F4=-37%2F3
x=%2837%2F3%29%2A%284%2F21%29
x=148%2F63
x=2 22/63
