x = 1

Explanation:

To solve an equation with the variable on two sides, first try to manipulate the equation so the variable is only on one side.

For example, we can subtract x from both sides.

4x-2-x = x-x+1 (combine like terms. x on the right side cancels out.)
3x-2 = 1 (add 2 on both sides to isolate the variable)
3x = 3 (divide by 3)
x = 1

Our final answer is x = 1

(To check that the answer is right, plug it in.
4(1)-2 = (1)+1
4-2 = 2
2 = 2 (if the equation is true, the final answer is correct.))
