Question

How do you solve `2x+2x+2=4x+2?`

Answer 1

If the problem is really how it's written, there is no single solution.

Explanation:

Since `2x+2x=4x` the equation turns into:

`4x+2=4x+2` which is true for ANY value of `x`

But if it were `2x^2+2x+2=4x+2` the story changes:

Divide by `2`
`->x^2+x+1=2x+1`

Subtract `2x` and subtract `1`
`->x^2-x=0`

Factorize:
`->x*(x-1)=0->x=0orx=1`
