Answer: Visual
Step-by-step explanation:
Visually analyzing the art work is an effective way
Angle 2 and angle 4 are vertical angles which makes them congruent
3y = 2x + 6
x + y = 7
y = 7 - x
3(7 - x) = 2x + 6
21 - 3x = 2x + 6
21 - 6 = 2x + 3x
15 = 5x
15/5 = x
3 = x
x + y = 7
3 + y = 7
y = 7 - 3
y = 4
Solution is (3,4)
