Understanding One-Step Equations

This video tutorial covers solving three application problems using one-step equations involving multiplication or division. The first example calculates the cost of one pound of strawberries by dividing the total cost by the number of pounds. The second example determines Marcella's car payment by dividing Ramon's payment by three. The final example finds Charlotte's age by multiplying David's age by four, demonstrating the use of fractions in equations.

What is the first step in solving a one-step equation involving multiplication?

• Add the same number to both sides

• Subtract the same number from both sides

• Multiply both sides by the same number

• Divide both sides by the same number
