Answer 1

Answer:

x = 10, y = -3 and m = -1

Step-by-step explanation:

Let E1 : 2x+3y=11 and E2 : x+3y=1.

On multiplying E2 with 2 and subtracting it from E1, we get

E1 : 2x + 3y = 11

E2 :2x + 6y = 2

     -     -         -

-----------------------------------

-3y = 9 or y = -3

On putting y=-3 in E1, we get

2x -9 = 11 or x = 10

Now, put x=10 and y=-3 in y=mx+7.

⇒ -3 = 10m+7

or -10 = 10m

or m = -1
