Question

I have to solve the system of linear equations by elimination. i also have to check my solution.

Answer 1

`x=1`,
`y=6`

Explanation:

Give.

`x+2y=13`----------(1)

`-x+y=5`------------(2)

Solve this linear equation by elimination method.

Add equation 1 and 2

`x+2y=13`

`-x+y=5`

-----------------------------

`0+3y=18`

`3y=18`

`y=(18)/(3) \\y=6`

Put y value in equation 2

`-x+6=5`

`-x=5-6`

`-x=-1`

`x=1`

`x=1`,
`y=6`
