Hello! The value of x+y is 12
Make sure to read an explanation so you can understand the solution better.
Any questions about the answer and explanation can be asked through comments.
Step-by-step explanation:
We can simply solve the system of equations by substituting x = 3y in the first equation

Therefore, the value of y is 3. Then we substitute the value of y in x = 3y.

Therefore, the value of x is 9.
Since you want to find x+y, simply add 9 and 3 as we get 12.
Therefore x+y = 12.
I am very confused on what you mean

Step-by-step explanation:
There are 14 male cousins and 10 female cousins.
Step-by-step explanation:
Let,
m be the male cousins and f be the female cousins
