Question

Which of the following is the solution of –6x – 17 = 19? x = –8 x = –6 x = 6 x = 12

Answer 1

x=-6

Explanation:

1. -6x-17=19

2. -6x=19+17

3. -6x= 36

4. x= 36/-6

5. x= -6

Answer 2

x = -6

Explanation:

If you wanted, you could plug each value into the equation, but the more efficient method would be to isolate x:

-6x - 17 = 19 add 17 to each side

-6x = 36 divide each side by -6

x = -6
