    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)
