You solve one of the equation for one of the variables. For example, if the variables involved are "x" and "y", you might solve for "y". It doesn't really matter what variable you solve for first, so you can solve for whatever variable is easiest to solve. Then - assuming you got, for example, "y = 3x -1", in this example you would replace every "y" by "3x - 1" in the other equation or equations.

Can quadratic systems be solved using elimination and substitution?
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.
How do you solve a problem using the substitution method?
You solve this by theoretically diverting the hypotenuse of the x divided by the overall beneficial procedure of y
How do you solve systems of equations by using elimination?
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
What is the disadvantage of using the substitution method in solving linear equations rather than the graph method?
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.
What are the pros and cons to using the substitution method to solve equations in algebra?
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.

What does GUESS stand for when using the guess method?
G-Given U-Unknown E-Equation S-Substitution S-Solve
When using the substitution method to solve a nonlinear system of equations you should first see if you can one variable in one of the equations in the system?
isolate
What is the advantage of using the method of substitution rather than using a graph?
Accuracy.
What are the pros and cons to using the substitution method to solve equations in algebra?
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.
What is an advantage of using the method of substitution rather than using a graph or table to solve a system of linear equations?
You will obtain a more accurate answer than is possible using graphical methods. It's faster and less work than using a table.
How do you solve a problem using substitution?
y=2x+9 and y=x+6
How do you solve Linear Equations with the substitution 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.
