It is the right triangle so add up to 90
==> 90-65 = 25
There's not enough information given to find a definite solution for the two numbers. Instead there will be many solutions. Two variable problems require either a second equation, a value for one of the variables or a relation given between them. (like if they're consecutive integers or one is twice the other)
So, what you can do is write out the equation and "guess and test" till you find two integers that work.
x^2 - y^2 = 9^2 - 1
x^2 - y^2 = 80
y = sqrt( x^2 - 80)
putting in integer values for x starting at 9.
1 = sqrt(81 - 80)
(9, 1) works likewise so would (-9,1) (-9,-1) as well as (12, 8)
Answer:
B. 39
Step-by-step explanation:
The total market share values of the stocks does not influence on the price-weighted index, as the index is simply obtained by the sum of all share prices divided by the number of different stocks. The price-weighted index of the three stocks is:

The answer is alternative B. 39.
First, add nine on both sides of the equal sign. Adding nine cancels the -9 out, whereas it changes 26 to 35.
Our current equation is 5w=35
Then divide by 5 on both sides, it has the same effect.
The answer to the equation is w=7
