6x + 3y = 27; y = (27-6x)/3; so for x>0 and y>0, X can not be more than 4.

so only 4 solutions with x=1,2,3,4 are possible.

A.P.Singh   14 years AGO

6x + 3y = 27; x, y are integral values and x, y > 0; 6x can not be more than 27. so x can have integral values of 1,2,3,4. and y will have corresponding values of 7, 5,3,1.

so only 4 solutions are possible.

6x+3y=27,
or, 2x+y=9,
or, y= 9-2x.
For y to be positive, the possible values of x are 1,2,3 and 4, for which the values of y are 7,5,3 and 1, respectively.
So, numbers of possible solutions are= 4..... Option 1)
