Understanding Equation Solving

The video tutorial explains how to solve an equation by isolating the variable. It begins by clearing parentheses and fractions using the least common denominator. The process involves distributing terms, simplifying fractions, and combining like terms. The solution is verified by substituting the value back into the original equation to ensure it holds true.

What is the first step in solving an equation with fractions?

• Clear parentheses

• Multiply by zero

• Isolate the variable

• Add fractions to both sides
