It is the first graph on e2020 :)
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
According to given statement;
m+f =24 Eqn 1
m= 2f - 6 Eqn 2
Putting value of m in Eqn 1
![2f-6+f=24\\3f=24+6\\3f=30](https://tex.z-dn.net/?f=2f-6%2Bf%3D24%5C%5C3f%3D24%2B6%5C%5C3f%3D30)
Dividing both sides by 3
![\frac{3f}{3}=\frac{30}{3}\\f=10](https://tex.z-dn.net/?f=%5Cfrac%7B3f%7D%7B3%7D%3D%5Cfrac%7B30%7D%7B3%7D%5C%5Cf%3D10)
Putting f=10 in Eqn 1
![m+10=24\\m=24-10\\m=14](https://tex.z-dn.net/?f=m%2B10%3D24%5C%5Cm%3D24-10%5C%5Cm%3D14)
There are 14 male cousins and 10 female cousins.

<h3><u>The value of y is -7.</u></h3><h3><u>The value of x is 8.</u></h3>
First we need to rearrange these equations so they line up properly.
6x - 2y = 62
-x + 2y = -22
Add equations together.
5x = 40
Divide both sides by 5.
x = 8
We can plug this value in to find the value of y.
6(8) - 2y = 62
48 - 2y = 62
Subtract 48 from both sides.
-2y = 14
Divide both sides by -2.
y = -7
