Answer :
Solve for x:
6x-3 (x+8) = 9
Distribute -3 over x+8.
-3 (x+8) = -24-3x:
6x+-24-3x = 9
Grouping like terms, 6x-3x-24 = (6x-3x)-24:
(6x-3x)-24 = 9
Combine like terms in 6x-3x.
6x-3x = 3x:
3x-24 = 9
Add 24 to both sides:
3x+(24-24) = 9+24
24-24 = 0:
3x = 9+24
9+24 = 33:
3x = 33
Divide both sides of 3x = 33 by 3:
(3x)/3 = 33/3
3/3 = 1
x = 33/3
Answer: x = 11
