Step-by-step explanation:

Step 1: Define Systems

y = 2x - 7

y = -x + 5

Step 2: Solve for x

Substitution

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

Step 3: Solve for y

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