${(x + 18)}^{\frac{1}{2}} + 2 = x$

Step 1

Subtract $x$ from both sides of the equation.

${(x + 18)}^{\frac{1}{2}} + 2 - x = 0$

Step 2

Reorder terms.

$- x + {(x + 18)}^{\frac{1}{2}} + 2 = 0$

Step 3

Graph each side of the equation. The solution is the x-value of the point of intersection.

$x = 7$
