Pinning as branliest for best explained answer :: 4x + 3y = 0
5y + 53 = 11x

solve : substitution method

sol:x=(5y+53)/11

value of x in 4x+3y=0

4×(5y+53)/11+3y=0

(20y+212+33y)/11=0

53y+212=0/11

y=-212/53

y=-4

now

value of x

4x+3y=0

4x+3×-4=0

4x=12

x=12/4

x=4

by solving both we get,

for a it would be 24 children.
