Solving One-Step Equations: Multiplication and Division

This video tutorial covers solving one-step equations using multiplication and division. It provides tips for solving equations, such as showing work, isolating the variable, and checking solutions. Two examples are demonstrated: solving 5x = 10 and x/-4 = 2. The video concludes with practice problems for viewers to try on their own.

What is the first step in solving one-step equations?

• Multiply both sides by the coefficient

• Identify the operation performed on the variable

• Divide both sides by the coefficient

• Substitute the solution back into the equation
