1-70.

Solve each of the following equations. Homework Help ✎

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 by x.

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

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

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

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

3. $(x+1)(x−3)=0$

Use the Zero Product Property.
