Answer 2

We have the following system of linear equation:

(1)
`x+6y=29`
(2)
`2x-4y=-6`

Let's apply elimination method by multiplying (1) by -2, then:


`-2(x+6y)=-2(29)`
∴
`-2x-12y = -58`

Next let's subtract (1) and (2):

(1)
`-2x-12y = -58`
(2)
`2x-4y=-6`
_______________________

`-16y=-64`
∴
`y=4`

Finally, substituting this value in (1) we have that:


`x+6(4)=29`
∴
`\boxed{x=5}`
