answer:

5-3a-18-a-1+8a=4a-14

Step-by-step explanation:

Work Shown:

5 - 3(a + 6) = a-1 + 8a

5 - 3a - 18 = a-1 + 8a ... distribute

-13 - 3a = 9a-1 combine like terms

-13 = 9a-1+3a add 3a to both sides

-13 = 12a-1

12a-1 = -13

12a = -13+1 ... add 1 to both sides

12a = -12

a = -12/12 ... divide both sides by 12

a = -1
