¡Espero que esto ayude! :)
Step-by-step explanation:
Given -
Equations
- x + y = 8
- x - y = 3
To Find -
- which pair of coordinates satisfies both equation
Now,
adding both equation, we get -
x + y + x - y = 8 + 3
2x = 11
x = 11/2
<h3>x = 5.5</h3>
Now, substituting the value of x on x + y = 8, we get -
5.5 + y = 8
y = 8 - 5.5
<h3>y = 2.5</h3>
Hence,
(5.5, 2.5) pair of coordinates satisfies both equations.

Answer:
12
Step-by-step explanation:
Average age of 5 boys = 11 year
Sum of age of 5 boys = 11*5 = 55
Age of sixth boy = 17 years
Sum of age of 6 boys = 55 + 17 = 72
Average age of 6 boys= 72/6 = 12
