How many solutions will this system of equations have? y = 3.5x - 3.5 y = -3.5x + 3.5

OpenStudy (anonymous):

A: No options. B: Infinite Options. C: One option. D: Two options.

OpenStudy (solomonzelman):

\(\large\color{black}{y = 3.5x - 3.5 }\) \(\large\color{black}{y = -3.5x + 3.5 }\) \(\large\color{black}{-3.5x + 3.5 = 3.5x - 3.5 }\) \(\large\color{black}{x=1 }\) when you plug in x=1, you get y=0 in either equation

OpenStudy (solomonzelman):

So, \(\large\color{black}{(1,0) }\)

So.. C?

if you substitute word "solution" instead of "option" then yes.
