Question

Which expression is equivalent to 17x − 8x + 2 and why?

2 − 9x, because (17x − 8x) + 2 = −9x + 2 = 2 − 9x

2 + 9x, because (17x − 8x) + 2 = 9x + 2 = 2 + 9x

11x, because 17x − 8x + 2 = 9x + 2 = 11x

7x, because 17x − 8x + 2 = 17x − 10x = 7x

Answer 10

17x and -8x are like terms. We can combine them

17x − 8x = 9x

think of it like

(17 xrays) minus (8 xrays) = 9 xrays

so the word problem could be "You have 17 xrays and someone takes away 8 of them. How many do you have left?" The answer would be 9 xrays
