Question

Solve for x. Give a reason for each step in the process.

5(-3a - 6) = 5a + 30

Answer 1

First distribute 5(-3a-6) which get you -15a-30 than combine like term if there are any and get the coefficient one side and the other on one side. Add 30 on both side which cancels out -30 leaving you with -15a=5a+60 now subtract 5 on both sides which give you -20a=60 now divide by -20 on both sides which give you a=-3
