Today in class...
We went over the homework to see if we had any questions about it and solved it together. Then we learned how to solve a 2 Step Equation. Here are the steps:
1. Isolate the variable
2. cancel the constant (integer) using its composite to make zero pairs.
3a. cancel variable to (1.)
4. Substitute to check.
Here is an example:
But, we didn't just learn how to show in that way. We also were shown how to show it by using Algetiles. Here is the example used in class:
That is how we use Algetiles to show 2 Step Equations! That is all we did in class. don't forget to do the homework we got.
