What we learned today was really confusing but I was able to figure it out by looking at each step carefully. I thought it would be a good idea to write my blog post about it because then if I forget or get stuck I can come back and read over it.
Substitution it pretty much what it sounds like, we use part of one equation to help us figure out the answer to another one.
We start by looking at the two equations, and decide which one would be easiest to start with.

We chose the the second equation because the y variable doesn’t have a coefficient so it’s easier. We use algebra to isolate the y by itself then we substitute the answer for y in for y in the first equation. Once that’s done we distributed the coefficient to into the brackets. After that we use Algebra to isolate x by adding 6 To both sides and adding the like Terms. Then we divide both sides by 11 and we’ve received the answer for x. X is the input nombre so we can go ahead and place that in the first spot of the coordinates. We’ve almost done no we just need to find the y coordinate. To do so we carry the answer we got for x which happens to be 3 and insert that into the second equation. And we use algebra to break that down and receive The y coordinate. You can see the break down highlighted in grey. Finally we put the two coordinates in brackets and we’re done.
