In this worksheet, students will practice solving systems of equations by using elimination or substitution.
Students solve each system and then write their answer in the appropriate blanks at the bottom of the page. They then add or subtract their answers as indicated to discover the super secret number.
As they finish, I tell them the super secret number. If their super secret number agrees with mine, they probably did the problems correctly.
A fun way to add excitement to practice problems!
Answer key is provided.
