Answer

Step-by-step explanation:

cancel out -9r on the right side by adding it to the left side. so then you get 11r-15=18 . then add 15 to the right to get 11r by itself . you'll get 11r=33 . divide both sides by 11 and you'll get r=3 ! :)

Angelina_Jolie [31]

Yes

Step-by-step explanation:

It's just like adding fractions where you have to find the common denominator so the fractions can be subtracted.

Example

$\displaystyle \frac{1}{2}-\frac{1}{3}=\frac{1*3}{2*3}-\frac{2*1}{2*3}=\frac{3}{6}-\frac{2}{6}=\frac{1}{6}$
