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
