Answer:
x = -1/4
Step-by-step explanation:
to solve for x, you can add or subtract the same thing from both sides of the equation so you get x by itself on one side.
if you start with
x + 3/4 = 1/2
you can subtract 3/4 from both sides to get rid of it on the x side
x + 3/4 - 3/4 = 1/2 - 3/4
x = 1/2 - 3/4
x = -1/4
