-2x + 8 = 14
Step 1: Bring 8 to the right side of the equation. To do this subtract 8 to both sides (this is the opposite of addition and will cancel 8 from the left side)
-2x + (8 - 8) = 14 - 8
-2x + 0 = 6
-2x = 6
Step 2: Isolate x by dividing -2 to both sides (division is the opposite of multiplication and will cancel -2 from the left side)
-2x/-2 = 6/-2
x = -3
Check:
Plug -3 where you see x and solve
-2(-3) + 8 = 14
6 + 8 = 14
14 = 14...............................Correct!
Hope this helped!
