Question

If the cost of a bike $x$ is twice the cost of a scooter $y$ , Respresent it using equations in 2 variables in the form $ax+by=0$

• A. x+2y=0
• B. x+y=0
• C. 2x-y=0
• D. x-2y=0

Answer 1

The correct option is D

x-2y=0

let cost of bike be $x$

cost of scooter be $y$

according to question $x=2y$

therefore linear equation will be

$x-2y=0$
