so you want to have only r on one side.
subtract 4 from both sides and then divide both sides by 5.
what do you get ?

the circle of 1/5 is full since r is also equal 1/5

if you started with
\[5r+4\leq 5\] then you should end up with
\[r\leq \frac{1}{5}\]

"less than or equal to"
keep the inequality the same (unless you multiply by a negative number, then switch it)
