Below is a set of equations. Sort the equations into 2 categories of your choosing. Then, sort the equations into 2 categories in a different way. Be prepared to explain the meaning of your categories. 100 = 8(x + 9) 9(x + 7) = 100 8(9 + x) = 100 (x + 7) * 9 = 100 100 = (9 + x) * 8 100 = 8x + 72 9x + 63 = 100 72 + 8x = 100 9x + 63 = 100 100 = 72 + 8x
