6x – 13 = 11
x= 4
A _____ is an unknown amount/quantity or value
A variable is an unknown amount/quantity or value.
3(2x - 9) = 3
x = 5
6m – 5m + 1
m+1
3x + 5 = 14
x= 3
___ ___ have the same variable or exponent. We combine these together
like terms
3x + 15 + 2x = -30
x = -9
-6(4x - 5)
-24x + 30
2x+13=−8
x= -42
_________ are positive and negative whole numbers. Like -1, 0, 9, -4...
integers
2 +9(x-1) = 2
x = 1
9 -3d(6 + 9)
9 - 45d
or
-45d + 9
2x+5=10
x= 2.5
a rule in math where we multiply the number outside to the terms inside the parenthesis.
What is The Distributive Property
2(x + 3) + 1 = 31
x = 12
4(5f + 3) + 11
20f + 23
3x−6=−3
x= 1
We know that an equation is already solved when the variable is already ________.
Hint: This means alone.
What is Isolated?
x = 8
3(5x - 2) + 9x - 4
24x - 10
