we can have two simultaneous equations here
where
let x represent children
and y represent adult
therefore
x+y=2200
1.5x+4y=5050
solving using substitution method
y=2200-x
substituting this in the second equation we get
1.5x+4(2200-x)=5050
1.5x+8800-4x=5050
3750=2.5x
x=1500
so we had 1500 children and 700 adults
