Which expression is equivalent to 2x-17?
a. -17+2x
b. -2x+17
c. -2x-17
d. 17+2x

The sum of algebraic terms has the commutative property, such as the sum of numbers. Remember that the commutative property says that a + b = b +a, t his is ther order of the numbers do not change the result of the sum. You just must be sure to keep the signs. So in this case 2x - 17 = -17 + 2x, and the answer is the optcion a. -17 + 2x.

Let`s start with expressions that are wrong: B ) - 2 x + 17 = - ( 2 x - 17 ) which is not equal to 2 x - 17. As for C ) - 2 x - 17 = - ( 2 x + 17 ), also wrong. D ) 17 + 2 x = 2 x + 17 , not equal to 2 x - 17. We know that : a + b = b + a. Therefore, the expression : - 17 + 2 x = 2 x - 17. A ) - 17 + 2 x Hope this helps. Let me know if you need additional help!
