Absolute Value on Both Sides

|2a - 10| = 6

• a = 8, a = 5

• a = 2

• a = 8

• a = 8, a = 2

Solve the absolute value equation. 

• {7}

• {-7, 7}

• {0, 7}

• No Solution

3| −8x| + 8 = 80

• {-7/3, 7/3}

• {-3,3}

• {11/3,-11/3}

• No Solution

Solve for x
l x−6 l + 4= 10

• x = 12 and x = 0

• x = 3 and x = -3

• x = -12 and x = 0

• No Solution

Solve for x. Write your answer with a comma between both numbers.

2|x-4| = 6

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 does not always have to be positive.

• Absolute value is like a clock it has only positive numbers.

• Absolute value is talking about distance, distance is always measured by positive numbers.
