Introduction to Solving One-step Equations Using Integers

What you’ll learn to do: Solve one-step equations using integers

A basket of apples sitting in the grass

The apples are picked–now it’s time to divvy them up!

After a day of apple picking, Jessica, Mark, and Kim decide to split up their apples equally. In their shared basket, they count [latex]39[/latex] apples total. How many apples can each of them take home? To find out, they’ll need to use division in a one-step variable equation. In this section, you’ll learn how to maintain equality on both sides of the equation and solve for a variable.
