Solving Linear Equations with Fractions

The video tutorial explains how to solve linear equations involving fractions by isolating the variable. It provides two examples: X + 3/4 = 5/9 and X - 1/6 = -1/15. The tutorial demonstrates how to manipulate equations to isolate the variable, find common denominators, and simplify fractions to find the solution.

What is the primary goal when solving a linear equation involving fractions?

• To multiply both sides by zero

• To eliminate all fractions

• To isolate the variable on one side

• To find the common denominator
