What is solution to 5x-x 12 plus 2x-710?

To solve the equation (5x - x + 12 + 2x - 710 = 0), first simplify the left side: combine like terms. This gives (6x - 698 = 0). Adding 698 to both sides results in (6x = 698), and dividing by 6 yields (x = \frac{698}{6} = 116.33). Thus, the solution is (x \approx 116.33).
