Answer:
-9x - 14
Step-by-step explanation:
Distribute (multiply) the 1/4 to everything in the parentheses.
1/4 * 4x = 1x or x 1/4 * -8 = -2
Then you distribute (multiply) the -2 to everything in the parentheses.
-2 * 5x = -10x -2 * 6 = -12
Then you put the equations together.
x - 2 - 10x - 12
Then you combine like terms.
x - 10x = -9x -2 - 12 = -14
Finally you get your answer in simplest form.
-9x - 14
