Question

If the cost of a bike x is twice the cost of a scooter y, the representation using equations in 2 variables in the form ax + by + c = 0 will be x - 2y = 0.

• A. x+2y=0
• B. x+y=0

Answer 1

The correct option is A

x+2y=0

Let, the cost of a bike be x.
The cost of scooter be y.
According to question x = 2y
Therefore linear equation will be:
$\Rightarrow x-2y=0$
