It is evident that you need to find the solution of the system, if it exists.

Let's work the equations.

The second equation (which corresponds correctly to the second statement) is:

g/2 - b = 2, which you can be transformed in this way:

1) Multiply by 2 => g - 2b = 4

2)  Transpose - 2b => g = 4 + 2b.

Now you can see that this equation is the same than the firs equation, which means that the second statement does not provide any new information.

Mathematically, this is a system with infinite solutions, and you cannot determine the number of boys or girls without more information which provides and independent equation.

Answer: there are infinite solutions to the system.

Pani-rosa [81]

Answer:

46 terms

Step-by-step explanation:

a₁=b, a₂₁= bₙ, d₁=9, d₂=4

n=?

---------------

a₂₁= a₁+20d₁= a₁+20*9= a₁+180

bₙ= b₁+(n-1)d₂= a₁+4(n-1)

a₁+4(n-1)=a₁+180

4(n-1)=180

n-1= 180/4

n-1= 45

n=46
