Answer:
one solution
Step-by-step explanation:
you multiply the 3 into the a and 6, and you multiply the -2 into the a and - 6. After that you would have 3a+18- 2a+12=6. Then -2a and 3a will go together to make 1a, and 18 and 12 will go together to be 30. Then you will move the six over and subtract it from 30 leaving a to equal 24.
