Question

find the value of k if X= 3 Y = 2 is a solution of the equation 3 X + Y = K find two more solutions of the resultant equation

Answer 1

Equation are x+y=6
And 2x+y=8

Answer 2

from 1st relation we get the value of k ...
i.e = (3)(3Y) + y = k
and (3)(3)(2/3) = k
i.e k = 6
and now for equation
3X + Y = 6
if X = 0 , Y = 6
if X = 1 , Y = 3
if X = 2 , Y = 0 ..
