2-21.

Solve each of the following equations.

1. $\frac{3}{x}+6=-45$

First, isolate the $x$-term by subtracting $6$ from both sides of the equation.

Multiply both sides of the equation $x$.

$x=-\frac{3}{51}\approx -0.059$

1. $\frac { x - 2 } { 5 } = \frac { 10 - x } { 8 }$

What can you multiply both sides of the equation by to eliminate the denominators?

$x=\frac{66}{13}\approx 5.08$

1. $(x+1)(x-3)=0$

Use the Zero Product Property.
