If x [-2 {-4(-a)}] + 5[-2{-2(-a)}] = 4a,...

If `x [-2 {-4(-a)}] + 5[-2{-2(-a)}] = 4a`, then x =

A

`-2`

B

`-3`

C

`-4`

D

`-5`

Text Solution

Verified by Experts

The correct Answer is:
B
`x[-2 {-4 (-a)}] + 5 [-2 {-2(-a)}]`
= 4a
`implies x(-8a) + 5 (-4a) = 4a`
`implies -8ax - 20a = 4a`
`implies -8ax =24 a`
`implies x=-3`
