Graphing is not necessarily easier than elimination or substitution. If you are good at drawing graphs, and do not like algebra, then graphing is easier. However, elimination and substitution are much faster, and graphing can often get awkward when working with more complicated formulae.

What is graphing tables and equations?
Which of the following is a disadvantage to using equations?
What are advantages to using the table method when graphing a linear equation?
For a linear I can see no advantage in the table method.
What type of integrand suggests using integration by substitution?
Integrands with a root, a power, a denominator, or an exponent on e
What is x y 3 and 3x - 4y - 19 solve using substitution?
2x-y=3 2/3x-y=-1
True or false The key to using the elimination method is to find variable terms in the two equations that have equal or opposite coefficients?
True
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.
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.
When is it best to solve a systems of linear equations using elimination?
Elimination is particularly easy when one of the coefficients is one, or the equation can be divided by a number to reduce a coefficient to one. This makes substitution and elimination more trivial.
How do you work out the point of intersection without a graph?
You use algebra and solve the system(s) of equations using techniques such as elimination or substitution.
How do you decide whether to use elimination or subsitution to solve a three-variable system?
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.
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 are the pros and cons of using the substitution or elimination method in equations?
Oh, dude, like, the substitution method is cool because you can easily solve for one variable and plug it into the other equation. But, like, it can get messy with fractions and decimals. The elimination method is great for getting rid of one variable right away, but it can be a pain to keep track of all those plus and minus signs. So, like, pick your poison, man.
How do you do substitution and graphing for 8thgrade?
To solve a system of equations using substitution, first solve one equation for one variable, then substitute that expression into the other equation. For graphing, rearrange each equation into slope-intercept form (y = mx + b) to find the y-intercept and slope, then plot the lines on the same graph. The point where the lines intersect represents the solution to the system. Both methods will yield the same result, confirming the solution is correct.
What to do when the coefficients of either variable are different?
When the coefficients of either variable are different in a system of equations, you can use methods such as substitution or elimination to solve for the variables. If using elimination, you may need to multiply one or both equations by a factor to make the coefficients of one variable the same, allowing you to add or subtract the equations effectively. For substitution, isolate one variable in one equation and substitute it into the other. This will help you find the values of the variables.
What is also called two or more linear equations?
Two or more linear equations are commonly referred to as a "system of linear equations." This system can involve two or more variables and is used to find the values that satisfy all equations simultaneously. Solutions to such systems can be found using various methods, including graphing, substitution, and elimination. If a solution exists, it can be unique, infinitely many, or none at all, depending on the relationships between the equations.
What is the difference between parentheses and brackets in graphing an equation?
None. Brackets are used as an alternative to parentheses. Using different symbols makes it easier to locate matching parentheses or brackets.
What is an advantage of graphing a line using slope intercept form instead of graphing using a table?
None. Different people prefer different ways of working.
