Solving Equations and Operations

The video tutorial explains how to solve an equation by isolating the variable x. It covers simplifying both sides of the equation, distributing terms, combining like terms, and using addition and subtraction to isolate x. The tutorial concludes with dividing to solve for x and verifying the solution by substituting back into the original equation.

What is the first step in solving an equation to find the value of x?

• Isolate x on one side of the equation

• Multiply both sides by a constant

• Divide both sides by a constant

• Add a constant to both sides
