Subtract होगा...
Because अगर subtract करेंगे तो हम v और u का value आसानी से nikaal सकेंगे.. लेकिन add kare toh woh aur bhi tricky hoga
___________________
6u + 9v =39
6u +4v =24
- __- ___-_
5v = 15
So v = 3
And u = (24 - 12) /6 = 2

Heya !!!
This is Your Answer...
Given :
6u + 4v = 24 (i)
6u + 9v = 39 (ii)
To solve it, we have to cancel out one value..
For this, we will subtract equation (i) from (ii),
6u + 9v = 39
6u + 4v = 24
(-) (-) (-)
-----------------
5v = 15
v = 3.
Putting v=3 in equation (ii),
6u + 9X3 = 39
6u = 12
u = 2.
Now, the Question arises why do we add? Why do we not subtract it?
Welll... We have to cancel the one value..
Lemme show you an example where we will add.. to cancel out..
Lets take..
2a + 3b = 6 (i)
a - 3b = 6 (ii)
Here we will add the two, and b gets cancelled.
2a + 3b = 6
a - 3b = 6
----------------
3a = 12
a = 4
and, b = -2/3
Hope You Got It
