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

Answer from: 24nelsoaddh

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
