Question

2x+y=14,x-y=1 in substitution method

Answer 1

Answer:

x = 5 , y = 4

Step-by-step explanation:

2x + y = 14.........(1)

 x  - y = 1..........(2)

add both equations, thus y gets cancelled

     3x = 15

       x = 15/3 = 5

put value of x in equ.(2)

 5 - y = 1

    - y = 1-5

    - y = -4

      y = 4
