Answer:
a=1
Step-by-step explanation:
7(5a-4)-1=14-8a
Distribute
35a - 28 -1 = 14 -8a
Combine like terms
35a -29 = 14 -8a
Add 8a to each side
35a+8a -29 = 14 -8a+8a
43a -29 = 14
Add 29 to each side
43a -29+29 = 14+29
43a = 43
Divide each side by 43
43a/43 = 43/43
a =1
7(5a-4) - 1 = 14 - 8a. Start off by multiplying 7by (5a-4).
35a - 28 - 1 = 14 - 8a. Combine like terms.
35a - 29 = 14 - 8a. Add 8a to each side and add 29 to each side.
43a = 43. Divide each side by 43.
a = 1
