Linear Equation Solving Techniques

The video tutorial explains how to solve linear equations by isolating the variable. It presents two methods: clearing fractions by finding the least common multiple and working directly with fractions. The first method involves multiplying each term by the least common multiple to eliminate fractions, while the second method combines fractions by finding a common denominator. Both methods lead to the same solution, demonstrating flexibility in solving linear equations.

What is the primary goal when solving a linear equation?

• To eliminate all constants

• To find the least common multiple

• To isolate the variable on one side

• To multiply all terms by zero
