x+4=-1
x+4-4=-1-4
x=-5
-----------------
5b=-25
5b%2F5=-25%2F5
b=-5
-----------------
3x+4=13
3x+4-4=13-4
3x=9
3x%2F3=9%2F3
x=3
-----------------
5(x-2)=15
5%28x-2%29%2F5=15%2F5
x-2=3
x-2+2=3+2
x=5
-----------------
x+8=3(x-4)
x+8=3x-12
x-3x=-12-8
-2x=-20
%28-2x%29%2F%28-2%29=%28-20%29%2F%28-2%29
x=10
