5x-6 = 2x+12
Combine like terms. Subtract 2x from both sides of the equation.
5x - 2x - 6 = 12
3x - 6 = 12
Add 6 to both sides.
3x = 12 + 6
3x = 18
Divide both sides by 3.
x = 18/3
x = 6
It looks like x does not equal 3. Let's try substituting 3 for x.
5x-6 = 2x+12
(5 * 3) - 6 = (2 * 3) + 12
15 - 6 = 6 + 12
Nope! 3 doesn't work.
You subtract 12 on both sides of the equal sign
Then you get 5x-18=2x
Subtract 5x on both sides
Divide by -3 both sides
You get x=6
Thank You That Is What I Got Also, But The Workbook Said x equaled 3
Im sorry but the books wrong
