2(3 – 4a) + 5(a – 7) what are the steps to solve this? please.
2 answers:
2(3-4a) + 5(a-7) first do the distributive property
6-8a + 5a-35 now combine like terms
-41 - 3a is the final answer
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
