Answer:

Only one solution

Explanation:

Solution,


- 6(x + 7) = - 4x - 2

Distribute -6 through the parentheses


- 6x - 42 = - 4x - 2

Move variable to L.H.S and change its sign


- 6x + 4x - 42 = - 2

Move constant to R.H.S and change its sign


- 6x + 4x = - 2 + 42

Collect like terms


- 2x = - 2 + 42

Calculate the sum


- 2 x = 40

Divide both sides of the equation by - 2


( - 2x)/( - 2) = (40)/( - 2)

Calculate


x = - 20

Hope this helps..

Good luck on your assignment..
