how do you solve a linear equation with a variable in the fraction

Question

8 - r/3 = 11, how wound you get the r alone, or off of the 3?

Answer 1

Multiply both sides of the equation by 3.

This technique is called clearing fractions. In general, if you want to clear fractions from an equation, you would multiply both sides of the equation by the LCD (Lowest Common Denominator) of all the fractions in the equation.
