if u either multiply or divide a number from one side, u must do the same calculation to the other side. hope that helps :)
Yes, it does. Because these points do respect the "law" that for each "x" there is only one "y" that corresponds to it
Is it a improper fraction or?
P + s = 200......p = 200 - s
20p + 15s = 3400
20(200 - s) + 15s = 3400
4000 - 20s + 15s = 3400
-20s + 15s = 3400 - 4000
-5s = - 600
s = -600/-5
s = 120 <=== there were 120 standard tickets sold
p + s = 200
p + 120 = 200
p = 200 - 120
p = 80 <=== there were 80 premium tickets sold
