Question

SOLVE 2x + 3y = 11 and 2x - 4y = -24 AND HENCE FIND THE VALVE OF m FOR WHICH y =mx - 1 *
​

Answer 1

ANSWER

m=-3

Step-by-step explanation:

2x+3y=11.....................1

2x-4y=-24...................2

subtracting 1 from 2 we get

2x-4y-2x-3y=-24-11

-7y=-35

y=5

putting value of y in eq 1

x=-2

y=mx-1

5=m(-2)-1

6=-2m

m=-3
