Equations with two unknowns

Find pairs of numbers that satisfy an equation with two unknowns; enumerate possibilities of combinations of two variables

What you'll learn

  1. 1

    Imagine you have two different types of fruit — 🍎 apples and 🍌 bananas. You want to find how many of each you have, but you only know the total and a clue!

  2. 2

    If there are 10 fruit total and 4 more apples than bananas, which pair could be right?

  3. 3

    Let's solve: a + b = 12 and a = b + 4

  4. 4

    Try this one: x + y = 15 and x = y + 3. Drag the numbers to make it work.

  5. 5

    If x + y = 15 and x = y + 3, what is y?

  6. 6

    Another type: 2x + y = 20 and x = 3

  7. 7

    If 2x + y = 20 and x = 3, what is y?
