Solving and Verifying Equations

The video tutorial explains how to solve an equation by isolating the variable. It begins with simplifying both sides of the equation using distribution and combining like terms. The tutorial then demonstrates isolating the variable by adding or subtracting terms. Finally, it verifies the solution by substituting the value back into the original equation, ensuring both sides are equal.

What is the first step in solving an equation?

• Multiply both sides by zero

• Divide both sides by the variable

• Isolate the variable

• Add numbers to both sides
