Question

checck whether the (3,1),(1,3),(0,8) are the solutions of the equation 3x-y=8

Answer 1

Hello

Step-by-step explanation:

3x-y=8

3x-y-8=0

then 1;=(3,1)

(3×2)-1-8=0

2;=(1,3)

(3×1)+(-1)-8=0

3;"(0,8)

(3×0)-(+8)-8=0

Answer 2

Step-by-step explanation:

(3,1)

3x-y=8

3*3-1=9-1=8

(3,1) in a solution.

(1,3)

3x-y=8

3*1-3=0

(1,3) is not a solution

(0,8)

3x-y=8

3*0-8=-8

(0,8)is not a solution
