Tickets to the school musical cost $3 for students and $5 for non students. Total ticket sales were $1790. The number of student tickets sold was 100 less than twice the number of non student tickets sold.

3s+5n = 1790

s = 2n-100

(s,n) = (190,280)

5n + 3n = 1790

n= tickets sold for non student

2n-100 = tickets sold for student

So,

5n + 3(2n-100)= 1790

5n + 6n - 300 = 1790

11n = 1790+300

11n= 2090

n= 190

So, substituting the value of n we 5(190)+ 3(2(190)-100) =1790

950 + 840 =1790
