5-38.

Solve each equation below. Think about rewriting, looking inside, or undoing to simplify the process.

$3\left(y + 1\right)^{2} − 5 = 43$
Hint (a):
Look at problem 5-3 for a reminder of these strategies.
Answer (a):
$y = 3 \text{ or }y = −5$

$\sqrt { 1 - 4 x } = 10$
Hint (b):
See part (a).
Answer (b):
$\textit{x}=-\frac{99}4{}$

$\frac { 6 y - 1 } { y } - 3 = 2$
Step 1(c):
Add $3$ to both sides.
Step 2(c):
Multiply both sides by y. Then finish solving.

$\sqrt [ 3 ] { 1 - 2 x } = 3$
Hint (d):
Start by cubing both sides.
