Answer 1

$\huge\sf\fbox{Answer}$

Question :

x +9y = 25, x + 17 y = 41 Find y

Solution :

As x is common in both the equation

We will cancel or subtract both the equations

But first we have to change the symbols of the second equation

from subtract (-) to add (+) and add(+)to subtract(-) =

• - x - 17y = - 41

Now,

• x + 9y = 25 - x - 17y = -41
• -8y = -16
• y = -16/-8
• y = 2

Answer :

2 ans
