Get the x on one side of the equation and the numbers on the other side.
First, use the distributive law to expand 4x(6 - 2)
4x(6 - 2) - 10 = 20
24x - 8x - 10 = 20
Combine like terms. 24x and -8x have the same variables.
24x + (-8x) = 16x
Now we have 16x - 10 = 20
We need to get ride of that -10. That way the 16x will be alone.
We need to subtract or add to -10 to make it to a 0.
We will add 10 to -10 to make it a 0.
Do the same thing with the other side.
16x - 10 = 20
16x = 30
Now divide both sides by 16 so the x can be alone.
x = 30/16
Change to a mixed number.
x = 1 14/16
Simplify
x = 1 7/8
