Six times a number increased by 20 is four less than eight times the number. Find the number

Greetings!

"Six times a number increased by 20 is four less than eight times the number. Find the number."...

This would be, as an equation:
 $6x+20=8x-4$

Solve:
Add 4 and -6x to both sides.
$(6x+20)+4+(-6x)=(8x-4)+4+(-6x)$
Simplify.
$24=2x$
Divide both sides by 2.
$(24)/2=(2x)/2$
Simplify.
$12=x$
$x=12$

x=12

Hope this helps.

Hello There!

An example of this would be:
$\frac{6}{1/4}$
6 = $\frac{6}{1}$
$\frac{6}{1} * \frac{4}{1}$
= $\frac{24}{1}$
= 24

Hope This Helps You!
Good Luck :)
