Inverse Operation

This resource covers the concept of inverse operations, focusing on addition and subtraction. An inverse operation reverses another operation, meaning that adding and subtracting the same number preserves the original value. For example, if you add 8 to 'x' to get 11, subtracting 8 from 11 returns you to 'x'. The resource includes an example problem for practice, demonstrating how to solve for 'x' in the equation x + 2 = 8, and checks the solution. Thanks to Mr. Imamura and Brianna Akau-Thomas for their contributions.

  1. Inverse Operation • MA.7.1.3: • By , • Period 1

  2. Inverse Operation An Inverse operation ‘reverses’ another operation. Addition and subtracting are inverses of each other. Because Adding and subtracting the same number does not change the original number.

  3. EXAMPLE X + 8 = 11 - 8 = -8 X = 3

  4. Problem • Solve for x • x+2 =8

  5. Solution! 8 - 2 = 6 subtract 8 by 2 =6 X + 2 = 8 - 2-2 X=6 Check: 6 + 2 =8

  6. Credits • Thanks to Mr. Imamura • Brianna Akau- Thomas • www.google.com • http://www.sparknotes.com/math/prealgebra/operations/terms/term_9.html
