Algebra | Systems of Two Linear Equations | Notes and Practice

Lesson Review Available

Review the foundation notes with TTA Pro Mr.O before solving. If this skill drill is part of an anchor lesson, the notes stay available during practice.

Objective: By the end of this lesson you can solve a system of two linear equations by substitution or elimination and say which is faster (Levels 1 and 2), read a solution off a graph or a table and classify a system as having one, none or infinitely many solutions (Level 3), switch between an equation, a graph, a table and a word problem and answer for an expression such as x + y rather than for x (Level 4), find the constant that forces no solution or infinitely many and handle a repeated bracket as a single unknown (Level 5), and finish a parameterised, tangency or point-family system inside 150 seconds without falling for the answer-form trap (Level 6).
