Putting the equation in desmos is the easiest way obviously. Substitution is in my opinion the easiest between the two ways.
Example: 5x+4y=10 <------ this is the equation we're are putting in y=mx+b| -3x-5y=7
Example: 5x+4y=10 <------ this is the equation we're are putting in y=mx+b| -3x-5y=7
Elimination is the one I have the most trouble with. Example:
5x+4y=10
-3x-5y=7
With elimination you want to try to get rid of one of the terms.
5x+4y=10
-3x-5y=7
