Math Problem Statement

Simplify the expression 3 - 17 - 9a + 2a.

Solution

The expression in the image is:

3179a+2a3 - 17 - 9a + 2a

Let's simplify this step by step:

  1. Combine the constants:
    317=143 - 17 = -14

  2. Combine the terms with aa:
    9a+2a=7a-9a + 2a = -7a

So the simplified expression becomes:

147a-14 - 7a

Here are some related questions to explore:

  1. How can we solve the equation if this expression equals a certain value (e.g., 147a=0-14 - 7a = 0)?
  2. How do you handle variables on both sides of an equation?
  3. What is the general approach to simplifying algebraic expressions?
  4. Can we factor out common terms from the simplified expression?
  5. How do you graph the expression 147a-14 - 7a?

Tip: Always group like terms (constants and variables) to simplify expressions efficiently.
