\left. \begin array | c | c | c | \hline x & y & = 3 \\ \hline x & 3 & \square & \\ \hline y & \square & 5 & 3 \\ \hline ( x , y ) & ( 3,0 ) & 5 & ( 0,3 ) \\ \hline \end array \right.

Answer»

For equationx + y = 3

If x = 3, y = 0(x, y) = (3, 0)

If y = 5x + y = 3x = 3 - 5 = - 2(x, y) = (-2, 5)

If y = 3, x = 0(x, y) = (0, 3)
