Solving for a variable first, then using substitution Sometimes using substitution is a little bit trickier. Here's another system of equations:

Learn to solve the system of equations -3x - 4y = -2 and y = 2x - 5 using substitution. Created by Sal Khan.

So at least for this example, it seems like the substitution method that this bird came up with worked just as well as the elimination method that you had originally done the first time you …

Yes. It doesn't matter which variable you select to eliminate. Assuming you have no math errors, you will get the same results for "n" and "q".
