Answer:

x =
(19)/(9)

Explanation:

First, make all the different parts into fractions with a common denominator, so that you can add and subtract them easily. In this case, the common denominator is four.

Doing this, you get
(3)/(4) x + (8)/(4) x = -(1)/(4) + (2)/(4) x + (20)/(4)

Isolate all the variables to get
(3)/(4) x + (8)/(4) x - (2)/(4) x = -(1)/(4) +(20)/(4)

Then, combine like terms
(9)/(4) x = (19)/(4)

Multiply both sides by 4 to get 9x=19

Divide both sides by 9, and you get
x= (19)/(9)

Hope this helps! :)
