1. ✡️Given✡️

   ★System of linear equations

   2x – y = 2

   x + 3y =15

   To find

   Value of x and y

   Solution

   ★Here, 2x – y = 2

   ⟹ y = 2x – 2___(i)

   Now

   ★⟹ x + 3y = 15____(ii)

   ★Substituting the value of y from (i) in (ii), we get

   x + 6x – 6 = 15

   ⟹ 7x = 21

   ⟹ x = 3____(iii)

   ★Substituting the value of x from (iii) in (i), we get

   y = 2 × 3 – 2 = 4

   ∴ x = 3 and y = 4

   ★Hence x = 3 and y = 4
