TODAY IN ALGEBRA… Learning Goal: 7.2 You will solve systems of linear equations by Substitution Independent Practice

7.2 SOLVING LINEAR SYSTEMS BY SUBSTITUTION STEPS FOR SOLVING A LINEAR SYSTEM BY SUBSTITUTION: STEP 1: Solve for 1 variable for one of the two equations (it doesn’t matter which equation you start with and which variable you choose to solve for). STEP 2: Substitute one equation into the other and solve for the given variable. STEP 3: Substitute the solution from STEP 2 into the equation you solved for from STEP 1 and solve for the given variable. THIS IS MUCH EASIER WITH AN EXAMPLE!
