Question

What is x if 2+ 9/4x=20

Answer 1

x = 1/8

Explanation:

Given:
`$ 2 + (9)/(4x) = 20 $`

Multiplying by 4x throughout, we will have:

⇒ 8x + 9 = 80x

⇒ 9 = 72x

Dividing by 72,

⇒ x =
`$ (9)/(72) $`

⇒ x =
`$ (1)/(8) $`

Substitute x = 1/8 in the given equation and it will give us 20. That means the value of 'x' identified is correct.

So, x =
`$ (1)/(8) $` is the required answer.
