9-52.

Solve each equation below. Check your solution.

$20-6\left(5+2x\right)=10-2x$
Hint (a):
Combine like terms after distributing.

$2x^2-9x-5=0$
Hint (b):
If you find it difficult to factor, try using the Quadratic Formula.

$\frac{3}{5x-1}=\frac{1}{x+1}$
Hint (c):
First, multiply both sides by the lowest common denominator.
Answer (c):
$x = 2$

$\left|2x-1\right|=5$
Answer (d):
$\begin{array}{r} 2x - 1 = 5 \\ 2x = 6 \\ x = 3 \end{array}$
or
$\begin{array}{r} 2x - 1 = -5 \\ 2x = -4 \\ x = -2 \end{array}$
