Good afternoon-night, class(;
Sorry because I didn't do the post before, but I couldn't do it.

Today we have started a new unit. Unit 4; the equiations.
We saw that an equality is composed of two algebraic expressions united by the equal sign and they can be True, or False; and Identities, or Equations.
Then, we saw the parts of an equation:

2x-3=3x+2

The first part; "2x-3" is the first member and it's composed by two terms, "2x" and "-3".

The second part; "3x+2" is the second member and of course it's composed by two other terms; "3x" and "+2".

If the equations have the same solution, they are called "equivalent equation".

Then, we copied some of the rules of the equivalent equations, but we didn't have time to finish that part.

Luckly, Mario didn't send us homework(;
