7x + 3 * (8 * 9)  =  1224                  We don't need to keep the parenthesees here.

 

7x + 3 * 8 * 9    =  1224                  Replace   3 * 8 * 9   with   216

 

7x + 216  =  1224                           Subtract   216   from both sides of this equation.

 

7x + 216 - 216  =  1224 - 216

 

7x  =  1008                                     Divide both sides of this equation by 7.

 

7x / 7  =  1008 / 7

 

x  =  144
