(QUICK!)Please answer this question, explain and show your work for brainliest! (systems of equations, either using elimination or substitution method!)

Answer:
Step-by-step explanation:
y = - 7x ......... (1)
- 14x - 2y = 0 ....... (2)
- 14x - 2y = 0 ⇒ y = - 7x
(1) and (2) are equivalent ⇒ system has infinitely many solutions
