Solving Equations and Checking Solutions

The video tutorial explains how to solve an equation by simplifying both sides, isolating the variable terms, solving for the variable, and verifying the solution. It begins with distributing and combining like terms, then moves to isolating the variable by subtracting terms. Finally, it solves for the variable by dividing and checks the solution by substituting back into the original equation.

What is the first step in solving an equation?

• Combining like terms

• Distributing to clear parentheses

• Subtracting variables

• Adding constants
