1. So,x = 2 and y =−1 is the solution of the equation 2x+y=3

   Step-by-step explanation:

   x=2 and y=-1

   2(2)+(-1)=3

   4+(-1)=3

   4-1=3

   3=3

   LHS=RHS.

   Pls mark my answer as brainliest and thank it!!!

2. • ” yes”

   WE ALREADY KNOW THAT ;

   x = 2 ; and y = -1 .

   So..

   • 2 × (x) + (y) = ?

   2 × (x) + (y) = ?

   Or; 2 × (2) + (-1)

   2 × (x) + (y) = ?

   Or; 2 × (2) + (-1)

   Or; 4 + (-1) = 3 …Answer
