   (i) x + y =5 and 2x –3y = 4

   By elimination method

   x + y =5 … (i)

   2x –3y = 4 … (ii)

   Multiplying equation (i) by (ii), we get

   2x + 2y = 10 … (iii)

   2x –3y = 4 … (ii)

   Subtracting equation (ii) from equation (iii), we get

   5y = 6

   y = 6/5

   Putting the value in equation (i), we get

   x = 5 – (6/5) = 19/5

   Hence, x = 19/5 and y = 6/5

   By substitution methodx + y = 5 … (i)

   Subtracting y both side, we get

   x = 5 – y … (iv)

   Putting the value of x in equation (ii) we get

   2(5 – y) – 3y = 4

   -5y = – 6

   y = -6/-5 = 6/5

   Putting the value of y in equation (iv) we get

   x = 5 – 6/5

   x = 19/5

   Hence, x = 19/5 and y = 6/5 again
