Question

Solve 6x + 2 = 2x - 14

Answer 1

x = - 4

Explanation:

6x + 2 = 2x - 14 ( subtract 2x from both sides )

4x + 2 = - 14 ( subtract 2 from both sides )

4x = - 16 ( divide both sides by 4 )

x = - 4

Answer 2

6x + 2 = 2x - 14

We move all terms to the left:

6x + 2 - (2x - 14) = 0

We get rid of the parentheses.

6x- 2x + 14 + 2 = 0

We add all the numbers and all the variables.

4x + 16 = 0

We move all terms containing x to the left hand side, all other terms to the right hand side

4x = -16

x= -16/4

x=-4
