Question

I need help on this problem.

Answer 1

1/2x=-1/6+1/2

3x=-1+3

3x=2

x=2/3

Answer 2

(9)
1/4x-1/2=(-1/4x)-1/6
lets simplify by moving the numbers so the variables are on one side and the numbers are on the other so that it looks like this 
1/2x=1/3 
divide 
x=2/3 
(12)
(-1/4x)+1/6=1/6x-1/9
same thing as last time 
(-5/12x)=5/18
x=(-90/60)
x=(-1 1/2)
x=(-1.5)
