Question

Solve 2x +3y =11 and 2x -4y =-24and hence find the value of m for which y
=MX+3

Answer 1

Answer:

2x+3y=11

2x=11-3y

Putting the value of 2x in eq 2

2x-4y=-24

11-3y-4y=-24

-7y=-35

y=5

x=(11-3(5))÷2

x=-4÷2

x=-2

y=Mx+3

5=-2M+3

2=-2M

M=-1

Answer 2

Answer :

M = -1

Step-by-step EXPLAINATION :

2x+3y=11

2x=11-3y

Putting the value of 2x in eq 2

2x-4y=-24

11-3y-4y=-24

-7y=-35

y=5

x=(11-3(5))÷2

x=-4÷2

x=-2

y=Mx+3

5=-2M+3

2=-2M

M=-1
