Question

write each of the following as an equation in two variable X =-5, y=2 , 2x=3 and 5y= 2​

Answer 1

x = 5 y = 2 2x = 3 2× 5= 10 5x2= 10

Answer 2

Answer:

Let the cost of pen be y and the cost of notebook be x

As per the question,

Cost of a notebook = Twice the cost of pen = 2y

So,

2y = x

x – 2y = 0

This is a linear equation in two variables to represent this statement
