Best ResponseYou've already chosen the best response.2Hmmm, let's see:\[(8 )  3 = 11\] \[11 + 4 = 7\] Remember that 2 times 2 is +4, so 7 is the answer

Best ResponseYou've already chosen the best response.2Oh ok, so for this equation, this is what it looks like:\[3 + 1(8)\] When you have a negative sign right before the parentheses, it can be shown like above. Now can you solve it?
