Question

How do you find the values of x and y given `[(9, 13)]=[(x+2y, 4x+1)]`?

Answer 1

`[9,13]=[x+2y,4x+1] rArr x+2y=9, &, 4x+1=13.`
`rArr x+2y=9, 4x=13-1=12 rArr x+2y=9,x=3.`
`rArr 3+2y=9 rArr 2y=9-3=6 rArr y=3.`

`:. x=3, y=3.`

Answer 2

`x=3,y=3`

Explanation:

`"equating corresponding components"`
