Question

Subtract the sum of (-5a + 3b - 7) and (4a + 2b + 5) from the sum of (2a – b + 12) and (-a + b).

Answer 1

Answer:

2a-5b+14

Step-by-step explanation:

• (-5a + 3b - 7) + (4a + 2b + 5)

        -5a+3b-7+4a+2b+5

        -1a+5b-2

• (2a – b + 12) + (-a + b)

        2a-b+12-a+b

        1a+12+0

        1a+12

Subtract:

(1a+12) - (-1a+5b-2)

1a+12+1a-5b+2

2a-5b+14
