Solving Systems of Equations Teacher Resources

Pupils relate real life situation to the equations, graphs and inequalities. They model real life scenarios using matrices and draw conclusions from their data. This lesson plan is aligned with FCAT.

Pupils write systems of equations in an augmented matrix and enter it into their calculator. They use the reduced row echelon function on the calculator to solve the system of equations.

Students solve linear equations using Cramer's Rule. In this algebra lesson, students use second order determinants to solve equations with two unknowns using a t-chart and identifying solution set. 

In this inverse matrices worksheet, students solve four systems of equations using inverse matrices.  Examples and explanations are provided.

Students solve systems of linear equations using substitution. They investigate the steps to solving linear equations by substitution and practice problems in small groups.

In this systems of equations worksheet, students solve 6 systems using the substitution method. Students then set up and solve 2 systems of equations word problems, one being a mixture problem.

In this quadratic linear systems of equations worksheet, students solve ten word problems using systems of equations.  The solutions are provided.

Students practice using algebra to be applied to real world situational problems. The key concepts of translation of language to algebraic expressions is covered. They also look in depth at relationships between different quantities.

Students solve word problems which involve graphing systems of equations. After discussing methods of solving word problems, the teacher demonstrates how to solve problems which involve graphing. They work together, at their desks, and...

Students solve word problems using systems of equation. In this algebra lesson, students use computer and graphing to graph and analyze their solution. They solve system involving inequalities.

In this interpretation of vectors and linear systems worksheet, students describe the geometric appearance of two vectors. They add the two vectors and sketch the sum as well as the vectors to determine the commutativity of vector...

In this graphical interpretation of vectors worksheet, learners execute operations of addition and multiplication by a scalar. They sketch results and determine the commutativity of vector addition. This three-page worksheet contains...

Students explore the relationship between distance and elapsed time. After writing a quadratic equation to exemplify the relationship discussed, students use inverse matrices to solve the unknowns. Using a motion detector and CBL...

Students analyze graphs to compare cell phone plans. In this algebra lesson, students work together to analyze phone plans and report the best phone plan. Students develop tables and graphs.

Learners explore how to use graphing calculators.

Tenth graders investigate the Elimination Method in the solving of equations. They solve the equation using this method in examples with the teacher and then transfer the new knowledge to independent practice.
