eg : x+2=3 , y-7 = (-4) , 3a-2 = 9+2 , b=4
Model 8 times a number plus 4 is 12
8n+4 = 12
Identify : 5y-6 = 19
variable = y
numerical coefficient = 5
constant = 6
Opposite Operations
+, -
x , ÷
- , +
÷ , x
a+1 = 3
a+1-1 = 3-1
a = 2
Sub
a+1 = 3
2+1 = 3
3=3
Reverse order of operation
4c-3 = 17
4c-3+3=17+3
4c÷4 = 20÷4
c = 5
Sub
4c-3=17
4c-3=17
4(5)-3=17
20-3=17
17=17
20-3=17
17=17

Hey Hey Hey Hannah. I really like you scribe post I like how you used different colours to know which on is which. I really like you video link and picture those things really help me a lot. I really like how well organized you did it. I lie how you made you font big for other people to see.
Well Good Job Hannah :)
Hey Hannah! I love your scribe post. It really help me a lot! I like how you change font color to make it really attractive. I also love the pictures, it really made me understand more about equations. You post is very well organize. The definitions help me a lot. The examples are also very helpful. To makes your post even better, I suggest you put more pictures.
The link and video also help me ..
