Question

Check grapcally whether the pair of equations 3x+5y=15 and x-y=5 is consistent. Also find the coordinates of the points where the graph of equations meet the y axis

Answer 1

heya
_______________________________

you can refer attachment with graph..
____________________________________

→ observing the graph we can see that lines are intersectng.

→ thus the following paur of equations are consistent and has only one solution.

→ coordinates of y are (0,3) ; (0,-5)

Answer 2

Answer:

Step-by-step explanation:

3/1 ≠ -5/1

Equations have unique solutions. Hence they are consistent.

X = 5+y

Put in equation (i)

3(5+y) + 5y = 15.

15 + 3y + 5y = 15

8y = 0

Y = 0

X = 5
