Answer 1

so from your last two problems I do not know if they were decimal points or multiplication but I viewed them as decimal points let me know if they are multiplication instead and I will fix it if I can. #1 is -3x - 7 #2 is 1/5x - 3 #3 is -3.2 B + 9 #4 is 6.5x + 1.7

Answer 2

below

Explanation:

combine like terms

1.) (−2x−5−3x)+(2x−2) =

-3x -7

2.) (2/5x−1)−(1/4x+2) =

(3/20x) - 3

3.) (−6. 5b+11) + (3. 3b−2) =

-3.2b + 9

4.) (−2. 6x+4. 2)−(3. 9x+2. 5) =

-6.5x + 1.7
