Answer

$x = 10$

Work Step by Step

We begin by combining like terms together to obtain the equation: $2x + 2 = 22$ Next, we isolate the variable $x$ by subtracting $2$ from both sides of the equation as shown below: $2x + 2 - 2 = 22 - 2$ Simplifying we have: $2x = 20$ We then divide through by the coefficient of the variable as shown below: $\frac{2}{2}x = \frac{20}{2}$ Simplifying, we have: $x = 10$ Therefore, the equation has a possible solution at the point $x = 10$
