Question

A student is solving the equation. 2x – 4 – (x + 2) = 6x If the student solves the equation correctly, what is the value of x ?

Answer 1

x =
`-(6)/(5)`

Explanation:

2x – 4 – (x + 2) = 6x is the given equation

Now simplifying both sides, we get

2x - 4 - x - 2 = 6x

taking like terms on each side of the equality, we get

2x - x - 6x = 4 + 2

or, -5x = 6

or x =
`(6)/(-5)`

hence, the value of x =
`-(6)/(5)`
