To solve for x, we will begin by using the distributive property

6x - 2(x + 4) = 12

6x - 2x - 8 = 12

(always remember to sort your negatives!)

Add like terms 

4x - 8 = 12

Add 8 to both sides

4x = 20

Divide both sides by 4

x = 5

6x - 2(x + 4) = 12    use distributive property

6x + (-2)(x) + (-2)(4) = 12

6x - 2x - 8 = 12      add 8 to both sides

4x = 20     divide both sides by 4

x = 5
