• Terms/Coefficients
• Coordinates (x, y)
• Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 2x - 7

y = -x + 5

Step 2: Solve for x

Substitution

1. Substitute in y:                                                                                                2x - 7 = -x + 5
2. [Addition Property of Equality] Isolate x terms:                                            3x - 7 = 5
3. [Addition Property of Equality] Isolate x term:                                              3x = 12
4. [Division Property of Equality] Isolate x:                                                       x = 4

Step 3: Solve for y

1. Define original equation:                                                                               y = -x + 5
2. Substitute in x:                                                                                                y = -4 + 5
3. Add:                                                                                                                 y = 1
