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.

Complete question :
The garden club earned $15 per hour by weeding neighborhood gardens for tt hours. A generous donor has agreed to double their earnings. How much did the garden club earn in all? Write your answer as an expression.
Answer:
($15t × 2)
Step-by-step explanation:
Given the following :
Amount earned per hour = $15
Number of hours = t
Amount earned for t hours = (amount earned per hour × number of hours)
= (15 × t) = $15t
Doubling this amount means multiply the amount earned by 2
= $15t × 2 = $30t
Answer:
26
Step-by-step explanation:
Devaughn = 2x
Sydney = x
x + 2x = 78
3x = 78
x = 78 / 3
x = 26
