Algebra I 807 is presented in two student-book parts: 807A and 807B. Students learn to solve systems of equations by graphing, substitution, and elimination. They also graph linear inequalities with two variables and solve systems of inequalities.

Problem-solving activities apply two-variable methods to percent-mixture problems and rate problems involving wind and current. Chapter reviews, a unit review, and a unit test give students opportunities to practice and assess these skills across both parts.
