Vocabulary
A constant variable or a number and a variable multiplied in an expression or seperated by + or -
4x + 6 +2x
6x + 6
3x = 9
x = 3
3(m-2)
3m - 6
3(2x + 10) = 54
x = 4
Defined Like Terms
Terms that have the same variable, power, or constant

10 = Z + 6
Z = 4
4 ( x + 8)
4x + 32

What is the Distributive Property
The number outside of the parenthesis tells us how many groups we will have of what is in it. We give the outside number to what is in the parenthesis by multiplying
7x + 6y +3
t + 19 = 2
t = -17
-7(x - 5)
-7x + 35
I solved 3 (2x + 10) = 48 and said x = 108
Is this the correct solution? If no, what is the correct answer?
No
x = 3
What is an an Inverse Operation and give me one example
The opposite operation/operations that undo each other
ex: add is the inverse of subtract
X + 3 - 5 + 4x - 2x
3x - 2
18 = a / 2
a = 36
9 (2x - 0 + 4x)
18x + 36x
54x
2(x + 10) = 60
x = 20
