About this worksheet

What students practice

Students solve linear equations with rational coefficients and variables on both sides.
Students use distribution and combine like terms to solve equations.
Students model shelter adoption and supply situations with linear equations.

How to use

Have students show equation steps on separate paper. Use the final section to check whether they can build equations and interpret their solutions.

Shelter Records: Adoptions and Supplies

Use rational-coefficient equations to check shelter records.

Record Checks

Solve each equation. Show steps on separate paper, and give exact answers.

A shelter receives x kilograms of dry food. Volunteers put 0.45x kilograms in one storage bin and 0.30x kilograms in another. Together, these bins hold 18 kilograms. Solve 0.45x + 0.30x = 18.

The delivery contained kg.

Solve the equation on a volunteer's practice sheet: (7/8)x − 3/4 = 25/4.

x =

A supply calculation gives 0.2(3x + 7) + 0.4(x − 2) = 9.6. Which value solves the equation?
