Hi there! The answer should be a = 5. I have included an image with the process. Hope this helps for future reference!

P.S. It is okay with me if you save the image for help later. :)

Answer:

a = 5

Explanation:

3(a - 4) + 1 = 9 - a Distribute the 3 into a-4

3a - 12 + 1 = 9 - a Combine like terms

[-12 and 1]

3a - 11 = 9 - a Add 11 to both sides to isolate 3a

+11 +11

3a = 20 - a Add a to remove it and have all a

+a +a

4a = 20 Divide by 4 to only have a

/4 /4

a = 5
