What are the different ways of solving systems of linear equations?

1) Graphing- If you graph the numbers you will easily be able to identify the answer.

2) Substitute- Substitute numbers in for x or y until they're equal on both sides.

EX: 2x+2=10

Substitute numbers in until you get a number that makes it equal on both sides

x= 4

3) Elimination- Eliminate numbers from both sides until they're equal.

Hope this helped! :)

a)(x-2)^2+(y-1)^2=9
