**(2x- 1)+(x-2)=3x+2**

**like terms**here it is,

**Terms that only differ by their coefficient. So Terms that have the same variable and exponent.**

**(x+3)+(3x-2)=4x+1**

**(3x-2)+(x+2)=4x**

**(3x+2)+(4x+1)=7x+3**

**(4x+1)+(4x)=8x+1**

**(7x+3)+(8x+1)=15x+4**

Now if you know how to do this you'll be able to do question 19. I'm just going to review how to subtract with algebra tiles so I don't need to go over #19.

eg. (6x+2)-(-9x+3)

You can add the opposite. So you change the minus to plus and make the numbers in the second bracket the opposite.

(6x+2)**+(9x-3)**

=6x+9x+2-3

=15x-1

Now here's how you do it with algebra tiles.

After that we worked on Extend, Review or the Chapter Test.

If you didn't finish it's homework

**Homework:**

Extend

Review of Chapter test

Journal (As always)

**Stuff due on Friday: (Stash-its)**

Kayaks for Rent or What Have You Got to Hide (Challenges)

Foldable

Self-Assessment

Math Links (Sheets)

Signed Test

**BTW the test is on Wednesday. And for next scribe I choose Aleiah!**
