Answer

137

Work Step by Step

First, complete the operations in the parenthesis (8 + 4) and (5 -2) and your equation looks like this now: 38 + 9 x 12 -3 (3). Next, complete the multiplication of 9 x 12 and 3 x 3 and now your equation is: 38 + 108 - 9. Lastly, add 38 + 108 = 146 and subtract 146 - 9 = 137.
