Question

X – 10y = 18
-6x – 10y = 32

Answer 1

Explanation:

`x - 10y = 18`

`-6x - 10y = 32`

Since both equations have
`-10y`, we can subtract the second equation from the first to try and solve for
`x`:

`(x - 10y) - (-6x - 10y) = 18 - 32`

`x - 10y + 6x + 10y = -14`

`7x = -14`

`x = -2`

With this, we can plug the value back into the first equation to solve for
`y`:

`(-2) - 10y = 18`

`-2 - 10y = 18`

`-10y = 20`

`y = -2`

Therefore, the solution is
`x = -2, y = -2`
