Which expression is equivalent to 2x - 17?

Answer 1

The expression equivalent to (2x - 17) is A.) -17 + 2x

Because 2x is positive in the first expression, it must stay that way. Because the minus sign is to the left of and modifying the 17, it must stay negative. Therefore, if you just switch the orders. A is correct.
