Answer 2

Is that (4)/(5x) or (4/5)x?

Answer 3

(4/5)x

Answer 4

There is two ways to do this...

(1) 4/5x + 4/3 = 2x --- multiply by LCD, which is 15
12x + 20 = 30x
20 = 30x - 12x
20 = 18x
20/18 = x
10/9 = x

(2) 4/5x + 4/3 = 2x -- subtract 4/5x
4/3 = 2x - 4/5x
4/3 = 10/5x - 4/5x
4/3 = 6/5x
(4/3) / (6/5) = x
4/3 * 5/6 = x
20/18 = x
10/9 = x

you arrive at the same answer...it just depends on if you want to work the equation with fractions in there or not
