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.
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.
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.
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

Graphical method sample problem: Find the solution to the system of equations: 2x + 3y = 12 x - y = 3 Analytical method sample problem: Solve the system of equations using substitution method: 3x + 2y = 11 4x - 5y = -7
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 -.

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.
