How do you solve #\frac{k}{5}-9\leq 12#?

Answer 1

Answer: #k<=105#

Oookaaay sooo. You treat this equation just like you would treat an equation with an equal sign. The first step is to add #9# to both sides. You then end up with #k//5<=21#. Then you do the opposite of the fraction and multply #5# by both sides. The #5's# cancel out. In result you get #k<=105#
