Solving Linear Systems of Equations - Substitution Method

Solving Linear Systems of Equations - Substitution Method. Recall that to solve the linear system of equations in two variables . we need to find the value of x and y that satisfies both equations. In this presentation the Substitution Method will be demonstrated. Example 1:.

SYSTEMS OF EQUATIONS

SYSTEMS OF EQUATIONS. Substitution Method. Ex. 1: 2x + y = 15 y = 3x. You now have to go back to one of your original equations where you will substitute the known value of x in order to determine the value of y. We have been using the Substitution Property in our proofs.

Solving Systems of Equations: The Substitution Method

Solving Systems of Equations: The Substitution Method. Example 1. Solve using substitution. y = 3x. 2x + 4y = 28. y = 3x. 2x + 4(3x) = 28. y = 3(2). 2x + 12x = 28. y = 6. 14x = 28. x = 2. (2,6). REMEMBER To Check: Always plug solution into original equations . Example 2.
