Question

How do you solve the following system?: `x + 2y = 6 , 7x -11 = -6y`

Answer 1

`x=-7/4,y=31/8`

Explanation:

writing your System in the form
`x+2y=6`
`7x+6y=11`
multiplying the first equation by b`-3` and adding to the second:
`4x=-7` so `x=-7/4` plugging this in the first equation:
`-7/4+2y=6`
so
`2y=6+7/4=31/4`
`y=31/8`
