I want to say -1. if you first combine like terms the equation would look like 2-2x. then next step i did was divide both sides by negative 2 to get the x by itself. after i did that i got -1 x.

Answer:
13/20
Step-by-step explanation:
Another way of asking this question is to ask for the difference of 1/4 and 9/10. The equation will start with 9/10 - 1/4.
9/10 - 1/4
Equations can only be added or subtracted when the denominators (bottom numbers) are the same. To do this, you must find a number that can be divided by both denominators. In this case, 20 can be divided by 4 and 10.
(9*2)/(10*2) = 18/20
(1*5)/(4*5) = 5/20
18/20 - 5/20 = 13/20
13/20 cannot be simplified as 13 is a prime number
13/20
