Answer:
no x = -8/13
Step-by-step explanation:
6x – (3x + 8) = 16x
Combine like terms
6x -3x -8 = 16
3x-8 = 16
Subtract 3x from each side
3x-8-3x = 16-3x
-8 = 13x
Divide by 13
-8/13 = 13x/13
-8/13 =x

to get the LCD we should start by doing a quick prime factoring of each denominator, as you see in the picture below.
the factors in red are the common factors to all values, and they are used in the LCD only once, the other not common factors in blue, they're used in the LCD.
The 3rd selection is appropriate.
___
(1/5)(5x) = x, so the inverse transformation returns the original. Not so for the other choices.
19 x (12 + 2 + 3) = 323
323 - (2 x 2) - (3 x (14 + 2))
= 323 - 4 - 48
= 271
