This week in math 10 we learned I learned how to use elimination to solve solutions, also I prefer substitution but eliminations is harder for me so I picked it.

Ex)

Next

First I multiplied the top equation by -2 so I can make zero pairs.

Then I simplified it.

Next I added both equations together to eliminate and combine both equations.

Lastly to get y by itself, I isolated it by dividing by 7 to each side.

To find x, I used the second equation ad substituted y with 3.

Then I simplified.

And I got x=3

The solution for the equations is (3,2)
