The three Math Idol judges have been eliminating contestants all day! The number of one-step equations and two-step equations who have been eliminated today is equal to 1150. If three times the number of one-step equations minus twice the number of two-step equations is equal to 1300, how many one-step equations auditioned today?

let x = number of one-step equations
    y =  number of two-step equations

x+y=1150
3x-2y=1300

x=720, y=430
