What role of operations that applies when you are solving an equation does not apply when your solving an inequality?"
No professions use order of operations. It is just a method of solving an equation.
When solving equations remember that whatever operations are performed on the LHS of the equation must be performed on its RHS to keep the equation in balance.
whats the difference between solving an inequality by algebriac vs graphical
None. Properties of inequalities are not that relevant when solving equalities.
In algebra, you perform the operations inside parentheses first.
In solving an inequality you generally use the same methods as for solving an equation. The main difference is that when you multiply or divide each side by a negative, you have to switch the direction of the inequality sign. The solution to an equation is often a single value, but the solution to an inequality is usually an infinite set of numbers, such as x>3.
What is the inherent meaning and justification of cross-multiplication as it applies to solving an inequality
No professions use order of operations. It is just a method of solving an equation.
The answer to the equation is p is equal to nine. You solve the equation by putting like terms together and then solving for p.
It's the same thing as solving an equation, the minor difference is to change the inequality sign when the numbers change signs(i.e negative to positive to negative).
When solving equations remember that whatever operations are performed on the LHS of the equation must be performed on its RHS to keep the equation in balance.

The difference is that instead of the sign "=", an inequality sign, for example "<" (less-than) is used. For solving inequalities, you can add, subtract, multiply or divide both sides by the same number, similar to an equation; however, if you multiply or divide by a negative number, the direction of the inequality changes. For example, "<" becomes ">".
You solve an inequality in exactly the same was as you solve an equation, by doing the same thing to both sides. The only difference is if you multiply/divide by a negative number, when you have to turn the inequality around.
usually used when solving an equation or inequality. Checking one's answer is plugging the answer back in the beginning to make sure you got the correct solution.
