Sagot :

We will use the next variables

x is the number of tickets sold for students

y is the number of tickets sold for adults

First equation

x+y=150

Second equation

3x+8y=1000

we isolate the x of the first equation

x=150-y

we substitute the equation above in the second equation

3(150-y)+8y=1000

450-3y+8y=1000

we sum like terms

5y=1000-450

5y=550

y=550/5

y=110

Then we substitute the value of y in the equation with x isolate

x=150-y=150-110=40

x=40 and y=110

The students sold

40 tickets for students

110 tickets for adults
