4-41.

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

1. $3(y + 1)^2 − 5 = 43$

See problem 4-8 for possible steps.

$y=3$ or $y=−5$

1. $\sqrt { 1 - 4 x } = 10$

Start by squaring both sides.

$x=-\frac{99}{4}$

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

Add $3$ to both sides.

Multiply both sides by $y$. Then finish solving.

1. $\sqrt [ 3 ] { 1 - 2 x } = 3$

Start by cubing both sides.
