Question

What are the differences between solving equations in one variable? and solving equations into variables? and what are the similarities?... PLEASE HELP ME IM STUPID ILL GIVE YOU 100 POINTS PLEASE!!!!! HAS TO BE 5 PARAGRAPHS LONG!

Answer 1

Answer:

Multiplying or dividing both sides by a negative number changes the direction of an inequality. So we cannot multiply or divide both sides by a variable unless we know that the variable is either always positive or always negative. This is not a concern when solving equalities.

When applying a decreasing function to both sides of an inequality, the direction of the inequality changes.

Swapping both sides of an inequality also changes the direction of an inequality. Again we don't have to worry about this with equalities.
