Answer:
emma: 6 toys, sally: 13 toys, james: 23 toys
Step-by-step explanation:
if emma had x toys, sally would have (x-3) toys. and we know that if james had 6 more toys, he would have the same amount as both girls combined. so in this case in terms of x, james would have (x+x-3-6) toys, after simplification we get 2x-9 toys..
since we know that the three of them have 52 nerf toys as total, we can set up the equation:
x= number of toys emma has
2x-9+x+x-3=52
4x-12=52
x=16
emma has 16 toys, and sally has (16-3)=13 toys. finally, james has (2*16-9)=23 toys. 16+13+23=52
