URGENT HELP PLEASE.. 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 eliminated today?

you can said that variables x = one-step equation y = two-step equation
OpenStudy (ivettef365):
then you have x + y = 1150
OpenStudy (ivettef365):

OpenStudy (ivettef365):
sorry the second equation is 3x - 2y = 1300
OpenStudy (ivettef365):
can you take it from there
