12(x + 9)= -108 : solve algebraically

Final

x = -18

Solution:

equation: 12(x + 9) = -108

Step 1: divide both sides by 12.

12(x + 9)     -108

=  

   12             12

           -108

x + 9 =   (solve -108/12)

              12

Step 2: subtract 9 in both sides.

x + 9 = -9

x + 9 - 9 = -9 - 9

Last  step: solve for x.

x = -9 - 9

x = -18
