Question

answer these questions fast, i will mark as brainliest.... please
1) if (3, 1) is the is a solution of the equation 3x+7y=m then m is

2) if the point (9,6) lies on graph with the equation of 5x= ky-3 then k is

3)the solutions of 5x+3y= 16 and 3x+5y=6

the one who will answer this is intelligent :)

Answer 1

Answer:

1) m=2

Step-by-step explanation:

x=3

y=1

3x+7y=m

3×3+7-1=m

m=2

verification

3x+7y=m

3×3+7-1=2

9-7=2

2=2

it is verified

I hope it is helpful!!!

Answer 2

Answer:

1) 16

2) 8

3) (2,2) and (-3,3)

Step-by-step explanation:

1) 3x+7x=m

3×3+7×1=m

16

2)5x=ky-3

5×9=k×6-3

45+3=6k

48/6=k

8

3) if (x,y) = (2,2)

5×2+3×2=16

10+6=16

16=16.

lly - if (x,y) = (-3,3)

3×(-3)+5×3=6

-9+15=6

6=6
