Question

Select all the expressions that are equivalent to 15 – 5x.

–5(x – 3)
3(5 – x)
–5(3 – x)
–3(–5 + 2x) + x
5(3 – x)'

Answer 1

-3(-5+2x)+x

Explanation:

First you have to use Distributive Property and multiply -5 and 2x by -3. you should have -6x+15+x. then you have to combine like terms but subtract -6x and x which gives us 5. your answer should be -5x+15. You can rearrange the answer to be 15 - 5x.

Answer 2

1)-5(x-3)= -5x+15
2) 3(5-x)= 15-3x
3) -5(3-x)= -15+5x
4)-3(-5+2x)+x=-5x+15
5)5(3-x)= 15-5x
Your answer would be 5) 5(3-x).
