Which oddered pair is the the system of equation?
Mnenie [13.5K]

Answer:

(3, -9)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination
  • Solving systems of equations by graphing

Step-by-step explanation:

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

-5x - 3y = 12

y = x - 12

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em>:                              -5x - 3(x - 12) = 12
  2. Distribute -3:                                 -5x - 3x + 36 = 12
  3. Combine like terms:                     -8x + 36 = 12
  4. Isolate <em>x</em> term:                               -8x = -24
  5. Isolate <em>x</em>:                                        x = 3

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define original equation:                    y = x - 12
  2. Substitute in <em>x</em>:                                     y = 3 - 12
  3. Subtract:                                               y = -9

<u>Step 4: Graph systems</u>
