x/2 = 3
x = 6

x / 2 - (7) = -4
x/2 = 3 <-- take the -7 to the other side, it changes to +7
x = 6 <-- Multiply both sides by 2
CHECK:
x / 2 - (7) = -4
6/2 -7 = -4
3 -7 =-4
-4 = -4

x - 7
-- = - 4
2
transpose 7 by adding both sides by 7
becomes:
x / 2 = -4 + 7
simplify:
x / 2 = 3
now to cancel denominator 2 just multiply both sides by 2/1 or just 2 ---> 2 [x / 2 = 3] 2
you get:
x = 3 (2)
Answer: x = 6
now substitute the value of your answer in x
6 / 2 - 7 = - 4
3 - 7 = - 4
=)

Add 7 to both sides.
x/2 - 7 = -4
x/2 -7 (+7) = -4 (+7)
x/2 = -3
Multiply both sides by 2
x/2(2) = -3(2)
x= -3(2)
x=6
tah daaah.

x/2 - 7 = -4
Add 7 to both sides
x/2 = 3
Multiply both sides by 2 because x is divided by 2
x = 6

x/2 - 7 = -4
2(x/2 - 7) = 2(-4)
x - 14 = -8
x = 6
