You can solve lineaar quadratic systems by either the elimination or the substitution methods. You can also solve them using the comparison method. Which method works best depends on which method the person solving them is comfortable with.
y=2x+9 and y=x+6
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.

They try to solve it using the scientific method.
The first step when using the scientific method is to state the problem you'll be attempting to solve.
Solve the problem using the + sign for the variable. Then solve the problem using the - sign for the variable. Report your answer as the answer that you got using + or the answer that you got using -.
pros; you will learn to be smarter. cons; you will waste ALL your time, get angry, and punch your teacher for making you do the work.
You will obtain a more accurate answer than is possible using graphical methods. It's faster and less work than using a table.
The answer depends on that the problem is!
You cant solve it unless it is an equation. To be an equation it must have an equals sign.
Multiply every term in both equations by any number that is not 0 or 1, and has not been posted in our discussion already. Then solve the new system you have created using elimination or substitution method:6x + 9y = -310x - 6y = 58
Using the scientific method, scientists can work together to test different hypotheses and determine the best solution for the problem
We slove problem on mixture by using the method called method of cross difference (cheaper / dearer) = (mean-cheaper)/(dearer-mean)
There is no simple answer. Sometimes, the nature of one of the equations lends itself to the substitution method but at other times, elimination is better. If they are non-linear equations, and there is an easy substitution then that is the best approach. With linear equations, using the inverse matrix is the fastest method.
You just plug in the value of the given variable. For example: y=3+2 2y=x (now you substitute y for 3+2) 2(3+2)=x (now solve the equation using distributive property) 6+4=x 10=x Tuhduh!! All done using the substitution property.
The graphical method is a method used to solve algebraical problems by using graphs.
No. you can't use water displacement method.
A system of equations is two or more equations that share at least one variable. Once you have determined your equations, solve for one of the variables and substitute in that solution to the other equation.
