Solve the following equation:
| 2x + 9| = 15
x = 3
x = 3 or x = −12
x = 3 or x = −6
x = 6 or x = −12
Solve the following equation:
|2a − 10| = 6
a = 8 or a = 5
a = 8 or a = −2
a = 8
a = 8 or a = 2

What's a way to define absolute value?
The value of a number
The distance of a number from zero
The opposite of a number
The multiplicative inverse of a number
What is the reason that absolute value is always written as a positive?
Absolute value is talking about numbers so it must be positive.
Absolute value is like a clock it has only positive numbers.
Absolute value does not always have to be positive.
Absolute value is talking about distance, distance is always measured by positive numbers.
Solve the following equation:
|−2n| + 10 = −50

What is the first step?
|x+7| + 5 = 6
Get the absolute value alone by dividing both sides by 5
Drop the absolute value bars and add 7 and 5 together
Get the absolute value alone by subtracting 5 from both sides
