Question

-7 (2r -1) + 3(8 -r )

Answer 1

You need to apply the -7 to both 2r and -1. You need to do the same with the 3, applying it to 8 and -r.

-14r + 7 + 24 -3r

Now you would want to combine like terms.

-17r + 31

Answer 2

First do the distributive property and then combine like terms. You should get -17r+31
