Answer 2

Answer:

a = 5

Step-by-step 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
