Equations
Find the missing value of the variable:
x + 3 = 7
x = 4
Are 3x + 1 and 2x + 2 equivalent expressions? Explain your thinking.
They are not equivalent expressions because they will not always give the same result for every value of the variable.
Use the distributive property to expand:
3(2x + 4)
6x + 12
50x + 200 = 1700

Are x and 1x equivalent expressions?
Yes they are equivalent expressions because they give the same result for every value of the variable.
Use the distributive property to expand:
4(5x - 1)
20x - 4
86 = 3x - 34
x = 40
What number do you get when you multiply all of the number's on a phone's number pad?

Find the missing value of the variable:
w/6 = 12
w = 72
Are x + x + x and 3x equivalent expressions?
They are equivalent expressions because they give the same result for every value of the variable.
Use the distributive property to expand:
4(2x-6)
8x-24
3(x + 4.5) = 36
x = 7.5
Pi
Find the missing value of the variable:
15y = 165
y = 11
Are 4x and 4x equivalent expressions?
They are not equivalent expressions because they do not give the same result for every value of the variable.
Expand:
7(2-x)
14-7x
-(2x - 6) = -2
x = 4
How many days are in 4 years? Hint: including a leap year
(365 x 4) + 1 = 1461
x2 = 64
x = 8
Are x3 and (x)(x)(x) equivalent expressions?
They are equivalent expressions because they give the same result for every value of the variable.
Expand this expression:
27(x + 3)
27x + 81
900 = -100(x - 3)
x = -6
