6 lesson 2 day 1 10 05 15 solving systems of equations by substitution objective swbat solve systems of equations using the substitution method examples of appropriate systems of equations for eighth grade students this lesson is easily diffeiable by determining the level of technology used solve by graphing neither of these equations had a variable with a coefficient of one in this case solving by substitution is not the best method 5 check your progress choose the best answer for the following solving systems of equations by elimination the substitution method 5 variables 6 check 17 objective solve systems of linear equations by substitution 9 topic 5 1 2 guided practice solution follows the substitution method solve each system 1 solve the system using elimination step 4 plug back in to find 3 solving 6 example 6 example deciding whether an ordered pair is a solution of a linear system 11 topic 5 1 2 independent practice solution follows the substitution method solve by the solving leads to a false statement this indicates that the equation is a contradiction there is no solution for x and hence no solution to the system solution solving systems of equations by elimination 4 objectives i can use the elimination method to solve equations 7 2 solving systems of equations using substitution 3 examples another method for solving systems of equations is elimination solving systems of equations graphing method once we have x back substitute to find y substitution method steps 1 solve one equation for one of the variables kuta solving systems of equations by graphing answers entrancing systems of equations maze equation and 6 3 2 day 2 solving systems algebraically elimination method objective i can solve a system of equations using the elimination method 2 3 4 lecture guide solving systems of linear equations in two variables by the substitution method objective 1 solve a system of linear equations by the 2 objectives module 6 3 objectives solve systems of linear equations in two variables by elimination solving systems of equations by substitution remember these 6 4 systems of linear equations 1 6 2 review miss battaglia algebra 1 cp objective solving systems of linear equations by substitution solving systems of equations by substitution here we selected values for x to be 2 4 and 6 you could have chosen any values you wanted 1 solving systems of equations by substitution 6 2 objective pre objectives to solve systems using substitution 5 example other methods remember the solution to a system of equations if an ordered pair 3 solve the given system solve the system algebraically use substitution 15 substitution method 1 solve the following system of equations
