Linear equations are a type of equation that has a straight line in the middle. There are several ways to solve a linear equation. They can be solved using single variables, multi-variable equations, two variables or a three-variable equation.
Single Variable Linear Equations – Two terms can be identified using one variable. Using two variables involves more steps than the single variable method.
Multi-Variable Linear Equations – A combination of two variables is used to solve for a linear equation. The first term determines the magnitude of the two subsequent terms, and the second term provides the direction of the line.
Two-Variable Multi-Variable Equations – The two variables are used to solve for a linear equation. This method is often used to solve for a multiple choice.
The third method involves the use of a spreadsheet to solve a linear equation. The spreadsheet contains columns for each variable. The first column has a label such as “x” for the variable “x”.
From the first column, the first row of the spreadsheet lists the first term of the equation. On the second row to the next row lists the second term of the equation, and so on.
Once a formula is selected it can be printed out on a different sheet of paper to view and work with different combinations of variables. By selecting the spreadsheet’s “print” option a copy can be made on another sheet of paper. These can then be entered into the spreadsheet to determine how the equation should be solved.
The Linear Equations Review Worksheet will help students understand and use the formulas for solving linear equations. It also helps students see the impact that different variables have on the formula. By using the results of their work they can practice different solutions to their problems.
