Question

Mohit and sahil are driving on two roads representation by the equation 2x+3y=7and 4x+6y=12.They drive within the speed limit will they meet up at any point What value is depected by mohit and sahil​

Answer 1

Answer:

No.

Step-by-step explanation:

Mohit's vehicle's speed=2x+3y=7

Sahil's vehicle's speed=4x+6y=12

By adding them;

2x+3y+4x+6y=7+12

6x + 9y = 19 ................ ( i )

So., we got this equation

By subtracting them;

(2x+3y)-(4x+6y)=7-12

2x-3y-4x-6y=(-5)

-2x-9y=(-5) ...................( ii )

By adding ( i ) and ( ii )

6x-2x+9y-9y=19-5

4x= 14

x=(7/2) OR 3.5

And, By eqn.

4(3.5)+6y=12

6y=(-2)

y=(-1/3)

Solving the eqn.

We get that values are different so they won't meet.
