Explanation:
4 - 5 y > 18
is in fact what is called an "inequality", not an equation. This is because the symbol that links the left side with the right side of the expression is not and equal sign but "<" or ">".
In order to solve for "y" in the inequality, you can operate similarly as you do with an equation (that is adding the same terms to both sides at the same time) and conserving the relationship. With the only difference that when you multiply or divide both sides by a negative number, you need to flip the direction of the inequality.
