How do I solve this inequality y4x-5?

What is the difference between inpuality and equation?
I assume you mean "inequality". An equation has an equal sign; an inequality has one of the inequality signs instead of an equal sign. These signs are: * Greater than * Greater than or equal * Less than * Less than or equal To solve an inequality, the main point to consider is that if you multiply or divide both sides by a negative number, you must invert the inequality sign. For example, if you multiply both sides by (-2), a greater-than sign would need to be changed to a less-than sign.
If you replace the equal sign of an equation an put an inequality sign in its place is there ever a time when the same value will be a solution to both the equation and inequality?
Yes, when the inequality has a less that or equal to sign, or a greater than sign or equal to sign, then the equal sign can be replaced and get a solution that is common to both the equation and the inequality. There can also be other solutions to the inequality, where as the solution for the equation will be a valid one.
Do you only flip the inequality when you divide by a negative number?
Yes you do, you also flip the inequality sign if you multiply by a negative # The > and < signs are strictly the "Greater than" and "Less than" signs. The inequality sign is an = with a / stroke through it. If you divide an inequality by -1 it remains an inequality.
What happens when both sides of a less than inequality are multiplied or divided by a negative number?
The inequality sign becomes greater than (>).
