Best ResponseYou've already chosen the best response.0I find the wording in this problem troublesom as well as the answer. I assume that you use the rule of order of operations and come up with something like this; 9x3=5x+7 or we might look at it like this 9(x3)=5(x+7) semantics. But irregardless how we look at it, the answer comes out as a fraction. When the problem states it is a number (whole number ???)
