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>
- Substitute in <em>y</em>:                              -5x - 3(x - 12) = 12
- Distribute -3:                                 -5x - 3x + 36 = 12
- Combine like terms:                     -8x + 36 = 12
- Isolate <em>x</em> term:                               -8x = -24
- Isolate <em>x</em>:                                        x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation:                    y = x - 12
- Substitute in <em>x</em>:                                     y = 3 - 12
- Subtract:                                               y = -9
