Can someone explain why, if 48 ÷ 2(9+3) = 288, then the reason why x doesn't equal 2 in the equation 48 ÷ x(9+3) = 288? Because I got x = 1/72. And I don't remember being taught that equations are ambiguous unless your dealing with absolute value or imaginary numbers, etc... such as in higher level math.
