To find out Ciarra's age, we need to set up an equation using the given information:
Let's assume Ciarra's age is represented by 'x'.
According to the information given, Nadia is 3 years younger than twice Ciarra's age. So, Nadia's age can be expressed as: 2x - 3.
It is also given that Nadia is 15 years old. So we can write the equation as:
2x - 3 = 15
To solve for 'x', we can add 3 to both sides of the equation:
2x - 3 + 3 = 15 + 3
2x = 18
Next, we need to isolate 'x' by dividing both sides of the equation by 2:
(2x)/2 = 18/2
x = 9
Therefore, Ciarra is 9 years old.
