Answer 2

Given : x=8

Y= 6

To find: Value of x when x=12

Solution:

when ,

X=8

Y=6

=X+Y (adding both numbers )

= 8+6

= 14

When x=12 then y=?

Using the same result:

Using X+Y =14

=>12 + Y =14 ( to find y when x is known )

=>Y =14 -12

we get,

=> Y = 2 ( x=12)

Answer: Value of Y=2 when x=12.
