Question

How do you solve the system of equations `y- 3x = 3` and `x - 2y = 4`?

Answer 1

`x=-2` and `y=-3`

Explanation:

We can take double the first plus the second to isolate `x`:

`2y-6x=6`
`-2y + x = 4`
`-5x = 10 implies x = -2`

Plugging that in to the first equation:
`y - 3(-2) =3 implies y + 6 = 3 implies y = -3`
