This short sequence draws ‘tables of values’ from linear and non-linear relationship outcomes to allow a high-intensity practice of substitution to solve - includes substitution of negative numbers. Emphasis on calculator use and looking for patterns in the independent variable row in order to identify symmetry and possible errors.

To find out, solve several one-step equations with your calculator and look for a pattern. To start, clear out any functions from the ( screen. Problem 1 – Addition Equations One way to solve an equation is by substitution, or trying different values for the variable until you find one that makes the equation true.
u substitution calculator with steps

Activity overview:
Students will use a graphing calculator to solve linear systems of equations in two variables using graphing features and table features. Students will then learn the algebraic methods of substitution and elimination. Students will identify which method is most appropriate for a given system, and use these systems to solve practical applications.
