Question -
Answer -
Equationis 2x – y = 6
(i) Solution is (3, 0) i.e. x =3, y = 0
Substituting the value of x and y in the equation
2 x 3 – 0 = 6 ⇒ 6 – 0= 6
6 = 6
Which is true
∴ (3, 0) is the solutions.
(ii) (0, 6) i.e. x =0, y =6
Substituting the value of x and y in the equation
2 x 0 – 6 = 6 ⇒ 0-6 = 6
⇒ -6 =6 which is not true
∴ (0, 6) is not its solution’
(iii) (2, -2) i.e. x = 2, y =-2
Substituting the value of x and y in the equation
2 x 2 – (-2) = 6 ⇒ 4 + 2= 6
⇒ 6 = 6which is true.
∴ (2, -2) is the solution.
(iv) (
,0) i.e. x = , y = 0,
Substituting the value of x and y in the equations
