3(x - 8) - 5 = 9(x + 2) + 1
First, you have to get rid of the parentheses:
3(x - 8) is the same as 3x - 24, so the left side is 3x - 29 .
9(x + 2) is the same as 9x + 18, so the right side is 9x + 19 .
Now, the equation is: 3x - 29 = 9x + 19
Subtract 19 from each side: 3x - 48 = 9x
Subtract 3x from each side: - 48 = 6x
Divide each side by 6 : - 8 = x
(I guess the answer is not 7.166 after all.)
