Answer:

(-2, -8)

x = -2

y = -8

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

13x - 6y = 22

x = y + 6

Step 2: Solve for y

Substitution

Substitute in x: 13(y + 6) - 6y = 22
Distribute 13: 13y + 78 - 6y = 22
Combine like terms: 7y + 78 = 22
Isolate y term: 7y = -56
Isolate y: y = -8

Step 3: Solve for x

Define original equation: x = y + 6
Substitute in y: x = -8 + 6
Add: x = -2
