Solve One equation for One variable( y= ; x= ; a=) 2. Substitute equation from step one into other equation (get an equation with only one variable) 3. Solve for the first variable. 4. Go back and use the found variable in step 3 to find second variable. 5. Check the solution in both Solving systems of equations with substitution can seem so abstract to students.

Play this game to review Algebra I. y = -2x + 18 y = 8 Substitution Method (Systems of Linear Equations) When two equations of a line intersect at a single point, we say that it has a unique solution which can be described as a point, \color{red}\left( {x,y} \right), in the XY-plane. The substitution method is used to solve systems of linear equation by finding the exact values of x and y which correspond to the point of intersection.

Then, see how to use that variable value to find the value of the other variable. Check it out! Play this game to review Algebra I. y = -2x + 18 y = 8 Substitution Method (Systems of Linear Equations) When two equations of a line intersect at a single point, we say that it has a unique solution which can be described as a point, \color{red}\left( {x,y} \right), in the XY-plane. The substitution method is used to solve systems of linear equation by finding the exact values of x and y which correspond to the point of intersection. Solving Systems of Equations by Substitution Solving a linear system in two variables by graphing works well when the solution consists of integer values, but if our solution contains decimals or fractions, it is not the most precise method. Solving Systems of Linear Equations by Substitution 4. Directions: On the following pairs of equations, solve for the value of x and for the value of y by following the steps.
