What is the solution to the equation?

7x + 6 = - 22

A. x = - 64/7

B. x = - 4

C. x = - 16/7

D. x = 4

7x + 6 = - 22.

+6 crosses equality sign and changes to - 6

7x = - 22 - 6

7x = - 28 Divide both sides by 7

7x/7 = - 28/7

x = - 4

Option B.

To solve the equation 7x+6 = - 22, we have to get the variable x alone on one side of the equation.

To do this, first we must subtract 6 from both sides, so that it cancels out with the + 6 on the left side.

7x + 6 = - 22 = 7x = - 28

Then, we must divide both sides by 7, so that we can get rid of the coefficient of the variable x on the left side of the equation.

7x = - 28 = x = - 4

Therefore, your answer is

B. x = - 4
