Answer:

x = (24/5) or 4+(4/5)

Explanation:

2x-4/5 = x + 4

2x -4/5 -x = x + 4 - x [Subtract x from both sides]

x - 4/5 = 4 [Simplify]

x - (4/5) + (4/5)= 4 + (4/5) [Add (4/5) to both sides]

x = 4 + (4/5) [Simplify]

x = 4*(5/5) + (4/5) [Convert 4 to a fraction with 5 as the denominator: Note that (5/5) is 1, and we can multiply 1 times anything. In this case it allows us to add the 4 and (4/5)]

x = 4*(5/5) + (4/5)

x = (20/5) + (4/5)

x = (24/5) or 4+(4/5)
