Question

what is answer for x-y=5​

Answer 1

Answer:

x = 4 , y = -1

Step-by-step explanation:

   solve by elimination ie eliminate x or y from the equations by performing operations on them.

   first label the equations , to follow the process.

   x - y = 5 ----------------(1)

   x+ y = 3 ----------------(2)

   If (1) and (2) are added then y will be eliminated.

   (1) + (2) gives : 2x = 8 → x = 4

   now substitute this value of x into either of the 2 equations and solve for y.

   let x = 4 in (1) : 4 - y = 5 → -y = 1 → y = -1

   check in (1) : 4-(-1) = 4+1 = 5

   check in(2) : 4 - 1 = 3
