Question

How do you solve `2x - x + 3= x - 7`?

Answer 1

X has no value. There is no solution to the equation.

Explanation:

`2x-x+3 = x-7`

Re-arrange the terms:

`2x-x-x=-7-3`

`0=-10`

This is obviously false but there is no longer an x to solve for?

This is an indication that this equation cannot be solved. There is no value of x which make the equation true.
