The school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Which equations represents the system that could be used? 

• 3s + 1c = 38 3s + 2c = 52

• s + c = 38 s + c = 52

• 3s + 3c = 38 1s + 2c = 52

Which of the following is not a method for solving systems of equations

• Substitution

• Estimation

• Graphing
