Updated: 4/28/2022

When you have a system of equations and you can solve for one in terms of th others and then replace it in the other equations that is substitution.

x+y=15

x-y=1

well the second one can be x=1+y

x+y=15 then can be (1+y)+y=15 by substitution.

1+2y=15

2y=14

y=7

Then x+7=15

x=8

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.

Why is substitution the best method in solving systems of equations?

It is not always the best method, sometimes elimination is the way you should solve systems. It is best to use substitution when you havea variable isolated on one side
