Answer:
In the first step, there is an issue when distributing the -3 to the terms inside of the parentheses. When multiplying the -3 to the -5, you would get an answer of +15, not -15.
The full correct process is:
(4m + 9) - 3(2m - 5) = 4m + 9 - 6m + 15
= 4m - 6m + 9 + 15
= -2m + 24
If you expand -9(-2x-3) you get 18x+27 (a minus times a minus is a positive) so the answer is A.
Answer:
wait what grade are you in ?
2x+2x+(x-15)=180
4x+x-15=180
5x=180+15
5x=195
x=195/5
x=39
Good luck
I really hope that helps cause I went all out and best of wishes!!
