Answer:

x = 12 1/2

Explanation:

Combine like terms, as follows: 25 - 30 = (4/5)x - (2/5)x, or

5 = (2/5)x

Multiplying both sides by (5/2) 'solves' this equation for x:

(5/2)(5) = (5/2)(2/5)x => (25/2) = x

Then x =25/2 or x = 12.5 or x = 12 1/2

Unknowns on one side, known on other.

2/5x - 4/5x = 30-25

-2/5x=5
X= -25/2
X=12.5
