Solve by graphing. 101 8 6 4 N -10 -8 2 4 02 6 8 10 -6 -4 -2 -2 -4 -6 oo -10 b. Solve the same system of linear equations by substitution. 3x + 6y = 18 - 3x + 6y = - 18 c. Solve the same system of linear equations by elimination. 3x + 6y = 18 - 3x + 6y = -18 d. Is the system consistent or inconsistent? Are the lines dependent or independent? Objective: To solve systems of equations using the substitution method. Essential Understanding: Systems of equations can be solved in more than one way. When a system has at least one equation that can be solved quickly for a variable, the system can be solved efficiently using the substitution method.
