Question

Solve x + 3y = 7 if x and y must be whole numbers.
(Points : 4)
{(0, 5), (1, 3), (2, 1)}

{(2, 1), (1, 4), (0, 7)}

{(1, 2), (4, 1), (7, 0)}

{(0, 5), (1, 4), (2, 1)}

Answer 1

You can substitute the given values in the equation, and see if they satisfy it or not.
Only the third one does so.
Put x=1 y=2
1+2*3=7
So, the equation is satisfied. Do u get this?
