Answer:

3(2 + 4x) = -7*2

6 + 12x = -7 * 2

6 + 12x = -14

-6 - 6

12x = -20

/12 /12

x = -5/3

Answer:


(-5)/(3)

Explanation:

3(2 + 4x) = -7 x 2 Distribute the 3

6 + 12x = -14 Subtract 6 from both sides of the equation

12x = -20 Divide both sides by 12

x =
(-20)/(12) Divide the top and the bottom of the fraction by 4

x =
(-5)/(3)
