For the 7: 30 show time, 140 movie tickets were sold. receipts from the $13 adult tickets and the $10 senior tickets totaled $1,664. how many adult tickets and how many senior tickets were sold? ? = adult tickets ? = senior tickets

We can take adult ticket as x and senior ticket as y.

Now we will form two equations

x + y = 140

13x + 10y = 1664

This system of equations we will solve using Gaussian algorithm (gradual elimination of the variables)  

We will multiply first equation with (-10) and get

-10x-10y=-1400 Than we will add to second equation and get

3x=264 => x=264/3=88 => x=88

Now we will replace x in the first equatin before multiplying and get

88+ =140 => y= 140-88= 52 => y=52

adult tickets x=88  and senior tickets y=52

Good luck!!!
