Answer:men=152 women=76 children=38
Step-by-step explanation:
- men+women+children=266
- men=4*children
- women=2*childrens
- so let say x represent the numebers of children the equatin becomes: 4x+2x+x=266
- solve for x =38 so the numbers of children is 38
- men=4*38=152
- women=2*38=76
First operation is to subtract
2x +5 = 10
2x +5 (-5) = 10 (-5)
2x = 5
Second operation is to divide
2x/2 = 5/2
x = 5/2
hope this helps :D
