Explanation / Answer
x = number of children tickets y=number adult tickets x+y=30 2x+5.5y=105.50 First multiply the top equation by -2 -2x-2y=-60 2x+5.5y=105.50 Now add the two equations together 3.5y=45.5 y=13 plug 13 in for y in one of the original equations to getx x+13=30 x=17 So Ron sold 17 tickets
