4-41.

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

$3(y + 1)^2 − 5 = 43$
Hint (a):
See problem 4-8 for possible steps.
Answer (a):
$y=3$ or $y=−5$

$\sqrt { 1 - 4 x } = 10$
Hint (b):
Start by squaring both sides.
Answer (b):
$x=-\frac{99}{4}$

$\frac { 6 y - 1 } { y } - 3 = 2$
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.
