Anna [14]

x = 10/27

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

9/5x = 2/3

  2. Multiply:                        90/135 = 2/3
  3. Simplify:                        2/3 = 2/3

And we have our final answer!
