Question

Solve for x nd y 2x+3y =11 , 2x-4y=-24 By cross multiplication method

Answer 1

ans-1

Step-by-step explanation:

2x+3y=11..........eq^n1

2x-4y=-24 .......eq^n2

substacting both equations,

7y=35

y=5

put y=5 in equation 1

2x+3(5)=11

2x+15=11

2x=11-15

2x=-4

x=-2

We have find value of m ,

y=mx+3

put ,y=5,x=-2

5=m(-2)+3

2m=-2

m=-1

the valule of m=-1
