Hi again Simon;
x-3/4=3/2x+1/2
x - 3/2x = 1/2 + 3/4
factor x
x ( 1 - 3/2 ) = 3/4
x (-1/2 ) = 5/4
x = (5/4) / (-1/2)
x = - 10/4
x = -5/2
Could you guess what my only reason is??? !!!
Good Luck.

x - 3/2 x = 1/2 + 3/4
-1/2 x = 5/4
x = 5/4 multiply by - 2
x = -5/2 = -2 1/2

Multiply the who bunch by common denominator (4), gives you
4x - 3 = 6x + 2
subtract 4x, then 2
-5 = 2x
x = -2 1/2

multiply everything by 4:
4x - 3 = 6x + 2
2x = -5
x = -5/2

x-5/4=3/2x
-5/4=5/2x
-5/4=10/4x
-5/4/10/4=x
5/4=x
