$x = 20$ $x=20$

In steps, isolate first the group that has $x$ $x$ in it. Then isolate $x$ $x$ .

Divide both sides by 6

$\sqrt{x + 5} = \frac{30}{6} = 5$ $sqrt(x+5)=30/6=5$

Square both sides

$x + 5 = 5^{2}$ $x+5=5^2$

subtract 5 from both sides

$x = 5^{2} - 5$ $x=5^2-5$

$x = 25 - 5 = 20$ $x=25-5 = 20$
