3x + 2y = 18

3x+2y -18 = 0  ........................(1)

a = 3 ; b = 2 ; c = -18 ;

let x = 4 , y = 3

then , 3x + 2y - 18 = ( 3 × 4 ) + ( 2 × 3 ) - 18 = 0

Hence x=4 and y = 3 is solution of the equation (1)

--------------------------------

Let x = 1 , y = 2

then , 3x + 2y -18 = ( 3 × 1 ) + ( 2 × 2 ) -18 = -11 ≠ 0

Hence x=1 , y=2 is not the solution of equation (1)
