Solving 2-Step Word Problems with Equations

This video tutorial teaches how to solve two-step word problems by writing equations. It begins with an introduction to equations, explaining them as balanced number sentences. The tutorial then presents two word problems involving insects at a zoo, demonstrating how to write and solve equations to find the number of beetles and ants. The lesson concludes with a review of the problem-solving process using equations.

If there were 20 insects in total and 12 were beetles, how many ants were there?

What happens to the number of ants when 7 ants are taken out from the initial count?
