Solving linear systems means to solve linear equations and inequalities. Then to graph it and describing it by statical statements.

What is the inherent meaning and justification of cross-multiplication as it applies to solving an inequality

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.

It really is utilized to solve specific variablesIt really is utilized to rearrange the word.

To solve linear equations, you always use the inverse operations

None. Properties of inequalities are not that relevant when solving equalities.

There is one linear inequality in 2 variables: l and x. That is not enough to obtain a solution.

If it is a linear function, it is quite easy to solve the equation explicitly, using standard methods of equation-solving. For example, if you have "y" as a function of "x", you would have to solve the variable for "x".

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.

That's going to depend on what statement the inequality itself makes, and on what you are required to find as a solution. There is no general rule for every exercise that involves an inequality. Sadly, you have no other choice but to use your brain every time.

This is not an inequality. There is no <,>, or = sign.

Unless it's a fancy graphing calculator, you don't. When solving an inequality, you need to solve it as an equality, remaining mindful of the proper direction of the inequality symbol after each step.

This isn't an inequality, since there is no less-than, greater-than, less-than-or-equal, or greater-than-or-equal sign. However, solving inequalities is similar to solving equations; however, when you multiply by a negative number, you must change the direction of the inequality sign.

Solve the inequality and enter your solution as an inequality comparing the variable to the solution. -33+x<-33

There is no equation not inequality. So there is nothing to solve!

You drink lots of beer and get really drunk. At that point, you won't need to solve it, dick.

There are more than two methods, and of these, matrix inversion is probably the easiest for solving systems of linear equations in several unknowns.

The above is not an inequality as stated.

Matrices are tools to solve linear equations. Engineers use matrices in solving electrical problems in circuits using Thevenin's and Norton's theories.

The main advantage is that many situations cannot be adequately modelled by a system of linear equations. The disadvantage is that the system can often get very difficult to solve.

I would not waste my time, because that's not an inequality.

A real number is not a question nor an equation or inequality that can be solved. There may be questions associated with real numbers that may be solved but that is not the same as solving the real number. The question is like asking how someone can solve you!

to solve a linear in equality you have to write it out on a graph if the line or shape is made ou of strate lines its linear

Even if you keep the decimal, later on you will still have to remove it. It is just an easier way to solve the equation.
