Solving Single-Variable Division Equations
Introduction

A division equation contains a variable divided by a number, and solving it requires applying the inverse operation. Multiplying both sides by the divisor isolates the variabl...

Emily is packing pencils into boxes. After packing, Emily sees that each of the six boxes holds nine pencils.

She wants to know how many pencils she started with. That total is unknown, so she represents it with the variable x and writes the single-variable division equation.

To find x, she uses multiplication, the inverse operation...
