Today in class, we made a

After Additive, we already proceed to the Subtractive Equations. Subtractive Equation's steps are the same with the additive.

note: as you can see, subtractive equation slightly different from additive because the constant of the subtractive equation is negative. . .

**c****olorful booklet**or a barn or booklet thingy. The colorful booklet's cover is**blue**so in case it gets lost people could easily recognize that the booklet belongs to someone from the room 8-73. Mr. Harbeck also gave us a**purple booklet**full of Algebra questions.First we discussed about Algebra Equation Solving Balance Scale and wrote it on the back of our colorful booklet.

here's the example:

the first step is to isolate the variable, second is to cancel using the opposite, third is to balance and then the last is to verify. . .

Right after that we disscused about Additive Equations. Additive Equations is also part of Algebra Equation Solving.The steps are also the same.

**Step 1- isolate the variable**

**Step 2- cancel using the opposite**

**Step 3- Balance**

**Step 4- Verify**

Here are some examples:

After Additive, we already proceed to the Subtractive Equations. Subtractive Equation's steps are the same with the additive.

Here are some examples:

For our homework, we have to do page 41 of our

**purple booklet**. Mr. Harbeck asked us to do the Additive and Subtractive Equations only, which were numbers 1, 3, 6, 8, 12, 13, 15, 18, 20, and 23.Uhhmm...that's about everything we did in class today.

and for the next scribe, I pick

**Brendan Moore.**Thanks for reading my scribe, please leave some comments you guyz. . . xD
