10-51.

Solve these equations, if possible. Each time, be sure you have found all possible solutions. Check your solutions.

$( x + 4 ) ^ { 2 } = 49$
Hint (a):
$\sqrt{(\textit{x}+4)^2}=\sqrt{49}$

$3 \sqrt { x + 2 } = 12$
Hint (b):
Divide both sides by $3$ .

$\frac { 2 } { x } + \frac { 3 } { 10 } = \frac { 13 } { 10 }$
Hint (c):
$\frac{2}{\textit{x}}=\frac{10}{10}$
Answer (c):
$x = 2$

$5 ( 2 x - 1 ) - 2 = 13$
Hint (d):
Distribute, then solve.
