Pre-Algebra

  • Order of Operations: BPEMDAS
  • Equality Properties

Algebra I

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

x + y = 15

-2x + 5y = -2

Step 2: Define variables

Given: x = 11

Step 3: Solve for y

  1. Define equation:                    x + y = 15
  2. Substitute in x:                       11 + y = 15
  3. Isolate y:                                 y = 4
