Diana's Unproject

In this unproject, Alyssa and I will be showing you how to do 2 step equation with dividing, multiplying, and distributive.

The steps for the dividing are:
Isolate the variable. Eg: x/2+6=11 ---> x/2=6-6=11
Constant (zero pair)
Balance it out, meaning what you do to one side you do to the other. Eg: x/2+6-6=11-6
Multiply the denominator with the numerator and what you do to one side, you do to the other.
Eg: (2)x/2=5(2) ----> x=10 





The steps for multiplying are:

1) Isolate the variable
2) Cancel the constant
3) Balance
4) Simplify
5) Cancel co-efficant (multiply or divide)
6) Balance
7) Simplify
Eg:
Ax+ b=c
3x+4=10
3x+4-4=10
3x = 6
3      3
X=2
3x+4=10
3(2)+4=10
6+4=10
10=10




What you have to do for Distributive Property:
You multiply the variable and the constant inside the bracket with the co-efficant number eg:
3(x-8)=12
The 3 is what you multiply by
The x-8 is what you multiply.
x-8
x-8
x-8
8x3=24
24-8=12
12=12
