Question

What is -2(1-4x)=3x+8

Answer 1

x = 2

Explanation:

`-2(1 - 4x) = 3x + 8`

`=> -2 + 8x = 3x + 8`

Lets keep the variables in L.H.S .

`=> 8x - 3x = 8 + 2`

`=> 5x = 10`

`=> x = (10)/(5) = 2`

Verification :-

Lets put x = 2 in the eqn.

In L.H.S -

`-2 (1 - 4 * 2)`

`=> -2 (1 - 8)`

`=> -2 * -7`

`=> 14`

In R.H.S -

`3 * 2 + 8`

`=> 6 + 8`

`=> 14`

∴ L.H.S. = R.H.S. (Proved)
