Mathdetailed explanation,. don't understand what i do after i move x over. so i'm stuck on -x=-3/4-1/2

Hello from MrBillDoesMath!

See Discussion below.

Discussion:

1/2 = x - 3/4                    => add 3/4 to both sides

1/2 + 3/4 = x - 3/4 + 3/4  => as -3/4 + 3/4 = 0

1/2 + 3/4 = x + 0  =>

x = 2/4 + 3/4

x = 5/4 = 1-1/4  

Thank you,

MrB
