General Formulas and Concepts:

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

10x + 6y = 14

-x - 6y = -23

Step 2: Solve for x

Elimination

Add 2 equations together: 9x = -9
Divide 9 on both sides: x = -1

Step 3: Solve for y

Define original equation: -x - 6y = -23
Substitute in x: -(-1) - 6y = -23
Multiply: 1 - 6y = -23
Subtract 1 on both sides: -6y = -24
Divide -6 on both sides: y = 4
