Multi-Step Equation
3x - 1 = 8
x = 9
⁴⁄₃ = ˣ⁄₆
x = 8
|x|=2
(-2, 2)
a number is less than -10
n < -10
2( x - 9) = -10
2x - 18 = -10
Distributive Prop.
9x + 1 - 7x - 5 = -20
x = -8
ʸ⁻³⁄₂ = ʸ⁄₅
y = 5
|x| = -3 - 2
No Solution
which property is this?
4 + (x + y) = (4 + x) + y
Associative
-6 = n
n = -6
Symmetric Prop.
12 - 2x = 9x + 45
x = -3
⁸⁄ₘ ₋ ₉ = ⁶⁄ₘ ₋ ₈
m = 5
-5 |6x + 21| = -15
x = (-3, -4)
Which Real Number set does 36/9 belong to?
Natural
What will my problem turn inti if I use addition Prop. of Equality on the equation:
8k - 4 = -20
8k = -16
3x - 13 = 7(x + 2) - 4(x - 7)
No Solution
⁷⁄₂ₓ ₋ ₈ = ³⁄ₓ ₋ ₆
x = 18
|⁴ˣ ⁻¹²⁄₂| = 8
x = (-1, 7)
If the length of one side of my square pool is 2x + 5. What is the perimeter in simplest form?
8x + 20
Where was mistake made below?
-8(w+1) = -5(w + 10)
-8w - 8 = -5w - 50
-13w - 8 = -50
-13w = -42
-5w was subtracted for -8w rather than added
4x = 38 - ½ (4x + 16)
x = 5
³⁄₁₆ₓ , ¹⁄ₓ ₊ ₁₃
x = 3
3 - ½ |r + 9| = -11
x = (-36 , 19)
four less than the product of a number and 7 is eight more than that number
7x - 4 = 8 + x
14 - 2x - 16 = 5x - 3x + 34
-2x - 2 = 2x + 34
