2 - 6x = x - 2 is a simple equation that can be solved to find a value for x. This can be done as follows:
Move the terms that contain "x" to one side of the equation, and other terms to the opposite side:
2 - 6x = x - 2
2 + 2 = x + 6x
Now add the terms together:
4 = 7x
And divide both sides by seven to solve for x:
4/7 = x
So x is equal to four sevenths, or 0.571428 repeating.
