Answer 1

Answer:

1:-x=2,y=3

2:-x=3,y=0

3:-x=1,y=6

3:-x=0,y=9

Step-by-step explanation:

1:-3*2=6 and 6+3=9

2:-3*3=9 and 9+0=9

3:-3*1=3 and 3+6=9

4:-3*0=0 and 0+9=9

Answer 2

Answer:

let x=1 so

3×1+y=9

y=9-3

y=6

so first solution is 1,6

let x=0

3×0+y=9

0+y=9

y=9

so second solution is 0,9

let x=2

3×2+y=9

6+y=9

y=9-6

y=3

so third solution is 2,3

let y=0

so , 3x+0=9

3x=9

x=3

so, the fourth solution is 0,3
