6-8a + 5a-35 now combine like terms

2(3 – 4a) + 5(a – 7)

Distribute 2  and 5 inside the parenthesis

Step 1:  2*3 - 2*4a + 5*a - 5*7

When we multiply it we will get

Step 2: 6 - 8a + 5a -35

Now we combine like terms. The terms that as same variables are like terms

-8a + 5a  is -3a

6 - 35 is -29

6 - 8a + 5a -35

Step 3: -3a -29

Final answer is -3a-29
