X=child y=adult x+y=142 --number of tickets 5.90x+9.30y=1031.60 --total sale
for this one, use the substitution method since youre finding the # of adult tickets sold, isolate the x-value on the first equation x=-y+142
plug -y+142 into all x values in the second equation
5.90(-y+142)+9.30y=1031.60 -5.90y+837.80+9.30y=1031.60 --distribute 3.40y+837.80=1031.60 --combine like terms 3.40y=193.80 --subtract across the sign y=57 --divide across the sign
divide 5,000 by 2,250 and you get 2 its like you have 0 quarters and you want to know how many you need to have to get 50 cent 50 divided by 25 equal 2 but your quistion answer is 2
