1. 
   `\boxed{y=6x}`

now lets place our equation

`4x+y=7`, since
`y=6x` we can substitute
`y` for
`6x`

`4x+6x=7\\10x=7\\x=(7)/(10)`

and since we said
`y=6x` we get that
`y=(42)/(10)`

`x=(7)/(10)\\x=0.7`

`y=(42)/(10)\\y=4.2`

Answer 2

Explanation:

y = 6x

so,

4x + y = 7

or, 4x + 6x = 7

or, 10x = 7

so, x = 7/10

Now,

y = 6x = 6 * 7/10 = 21/5
