Question

How do you find the values of x and y given `[(x, y)]=[(2y, 2x-6)]`?

Answer 1

`x=4, y=2`

Explanation:

corresponding coordinate must be equate. It means:
`x=2y....(i) and y=2x-6....(ii)`
putting the value of 'ii' in 'i' we have
`x=2(2x-6)`
`x=4x-12`
`3x=12`
`x=12/3`
`x=4`

Now put it into 'i'
`x=2y`
`4=2y`
`y=4/2`
`y=2`
