Say, no of children =x
no of adults =. y
x+y = 223
1.5x+4y=622
Solving these two equations
x=108
y=115
So, children=108
adults= 115

Hello Dalai,
Multiply the first equation by 4 giving you ----
4x+4y= 892
1.5x+4y=622
Subtract the two equations
2.5x=270
x=270/2.5=108
Substitute back to get y
Hope that helps you
