Which Variable to Solve For

Use this activity to practice how to solve for different variables in different types of problems.

1.Make a copy of Which Variable to Solve For Task Statements.

2. If you need to review how to solve for variables, watch the video on the left.

Problem-Solving Task

Work on this task 10-15 minutes each day. It may take 3-5 days to find solutions. If you have a cell phone, you can take a picture of the problem on the left and use the edit function to mark on it.

1. Copy the number towers on the left onto a piece of paper.

2. Complete the number tower by writing algebraic expressions in the empty boxes

3. Use the completed number tower to show that 2x+ y = 14 and x+ 2y= 16.

4. Find values of x and y that satisfy both equations: 2x+ y = 14 and x+ 2y= 16.
