Question

8x - 12= 4x please help...

Answer 1

8x - 12 =4x

Subtracting 4x from both sides: (because subtracting equal numbers from both sides does not change the equality)

Answer 2

8x -12 = 4x
-4x -4x
4x -12 = 0
+12 +12
4x / 4 = 12 /4
x = 3

Answer 3

8x-12-4x = 4x-4x;
or, 4x-12 =0

Answer 4

we want to get all the x terms on one side and everything else on the other side.
8x - 12 = 4x --- subtract 8x from both sides
8x - 8x - 12 = 4x - 8x -- combine like terms
-12 = - 4x -- now divide both sides by -4
-12/-4 = x
3 = x
check..
8x - 12 = 4x
8(3) - 12 = 4(3)
24 - 12 = 12
12 = 12 (correct)

x = 3

Answer 5

or, 4x = 12;
Dividing 4 from both sides: (dividing equal number from both sides does not change equality)
x =12/4 =3

Answer 6

Thank you :)
