Note the equal sign, what you do to one side, you do to the other.
10x - 4 = 2x + 12
Isolate the variable (x). First, add 4 and subtract 2x from both sides.
10x (-2x) - 4 (+4) = 2x (-2x) + 12 (+4)
10x - 2x = 12 + 4
Simplify. Combine like terms.
10x - 2x = 12 + 4
8x = 16
Isolate the variable (x). Divide 8 from both sides
(8x)/8 = (16)/8
x = 16/8
x = 2
2 is your answer for x.

10x-4=2x+12
First, add 4 to both sides
10x-4+4=2x+12+4
10x=2x+16
subtract 2x from both sides
10x-2x=2x-2x+16
8x=16
divide via by 8
8x/8=16/8
x=2
