There is no question. But I'd gladly help if you had a question!
The correct answer is: "The y's because the coefficients are the same."
Further explanation:
we always try to eliminate the variable from the system of equations which involves lesser calculations and complexity.
Assuming that Given equations are:
Equation 1: 82x + 2y = 30
Equation 2: 70x + 2y = 24
we can see that the coefficients of x are very large and different. While the coefficients of y are same. We can only subtract the equations to eliminate y.
Hence,
The correct answer is: "The y's because the coefficients are the same."

Answer:
15 feet..
taking base as 8m
Given: ladder = 17 m and base = 8 m
The ladder forms a right triangle with the base of 8 m, the wall will be 15 m and the ladder (hypotenuse) is 17 m.
Let’s say you did not know that this was a standard 8–15–17 right triangle.
This is how you can figure it out:
hypotenuse(h)22 = side2112 + side2222
Let side11 = base and side22 = wall
1722 = 822 + wall22
wall = 172−82−−−−−−−√172−82
wall = 289−64−−−−−−−√289−64
wall = 225−−−√225
wall = 15 feet
