Answer 3

To solve the system of equations, we can substitute the value of $y$ from the second equation into the first equation:

$x - (-1) = 5x + 2$
$x + 1 = 5x + 2$

Now, we can solve for $x$:

$1 = 5x + 2 - x$
$1 = 4x + 2$
$4x = -1$
$x = -1/4$

Now that we have the value of $x$, we can substitute it back into the second equation to find the value of $y$:

$y = -1$

So the solution to the system of equations is $x = -1/4$ and $y = -1$.
