1-70.

Solve each of the following equations.

$\frac{3}{x}+6=-45$
Hint (a):
First, isolate the $x$ -term by subtracting $6$ from both sides of the equation.
More Help (a):
Multiply both sides of the equation $x$ .
Answer (a):
$x=-\frac{3}{51}\approx -0.059$

$\frac { x - 2 } { 5 } = \frac { 10 - x } { 8 }$
Hint (b):
What can you multiply both sides of the equation by to eliminate the denominators?
Answer (b):
$x=\frac{66}{13}\approx 5.08$

$(x+1)(x-3)=0$
Hint (c):
Use the Zero Product Property.
