Answer:
4x - 4
Step-by-step explanation:
Combine like terms. Like terms are terms with the same variable as well as the same amount of variables:
6x - 2x + 2 - 1 - 4 - 3 + 2
(6x - 2x) = 4x
(2 - 1 - 4 - 3 + 2) = (2 + 2) + (-1 - 4 - 3) = (4) + (-8) = -4
4x - 4 is your answer.

-9/4v + 4/5 = 7/8;
First, you subtract 4/5 from each side to have variable v on a side and numbers on the other:
-9/4v = 7/8 - 4/5;
-9/4v = 35/40 - 32/40;
-9/4v = 3/40;
Then you divide each side to get the variable v alone on a side, and one number on the other:
V= (3/40) / (-9/4);
Dividing to fractions is equal to multiplying the first one by the inverse of the second:
V= (3/40) * (-4/9);
V= -12/360;
V= -1/30;
You can re-check your answer (very important):
(-9/4)*(-1/30)+4/5=7/8;
The answer has been approved.
