Answer;
If the inequality states something untrue there is no solution. If an inequality would be true for all possible values, the answer is all real numbers, To solve an equation means to find all numbers
that make the equation true. The numbers are
called solutions or roots of the equation. A
number that is a solution of an equation is said to
satisfy the equation, and the solutions of an
equation make up its solution set. Equations
with the same solution set are equivalent
equations.
