We need to solve the next inequality:

$n-5\leq5n-1$

First, add both sides by 5

$n-5+5\leq5n-1+5$
$n\leq5n+4$

Now, subtract both sides by 5n:

$n-5n\leq5n-5n+4$
$-4n\leq4$

To find n, we need to multiply by -1 on both sides, this will invert the

inequality. Therefore, we change "≤" to "≥".

$(-1)(-4n)\ge(4)(-1)$
$4n\ge-4$

Finally, divide both sides by 4:

$(4n)/(4)\ge-(4)/(4)$

Then

$n\ge-1$
