Question

Solve. 1/2(4x + 2/5) = 4/5

Answer 1

`(1)/(2)(4x + (2)/(5) ) = (4)/(5)\\2x + (1)/(5) = (4)/(5)\\(10x + 1)/(5) = (4)/(5)\\10x + 1= 4\\10x = 3\\x = (3)/(10)`

Answer 2

x = 3/10

Explanation:

Given equation,

→ 1/2(4x + 2/5) = 4/5

Let's solve the problem,

→ 1/2(4x + 2/5) = 4/5

→ 2x + (1/5) = 4/5

→ 2x = (4/5) - (1/5)

→ x = (3/5) × (1/2)

→ [ x = 3/10 ]

Thus, the value is 3/10.
