1. Given Equation

   2x + y = 5 (i)

   3x – y = 5 (ii)

   To Find the value of x and y

   Now we using Substitution Method

   So, Take (i)

   2x + y = 5 (i)

   y = 5 – 2x (iii)

   Put the value of y on (ii)

   3x – y = 5

   3x -(5 – 2x) = 5

   3x -5 + 2x = 5

   5x = 5 + 5

   5x = 10

   x = 10/5

   x = 2

   Put the x = 2 on (iii)eq

   y = 5 – 2x (iii)

   y = 5 – 2×2

   y = 5 – 4

   y = 1

   Answer

   x = 2 and y = 1
