Question

y = 2x + 3
2y = 4x + 6
The system of equations has _____ solution(s).
no
one
infinite

Answer 1

both represent the same line
so the answer should be obvious

Answer 2

one?

Answer 3

\(\Large \color{purple}{\rightarrow 2(y) = 2(2x + 3) }\)
\(\Large \color{purple}{\rightarrow 2y = 4x + 6 }\)

So:

\(\Large \color{purple}{\rightarrow 4x + 6 = 4x + 6 }\)
\(\Large \color{purple}{\rightarrow 4x = 4x }\)
\(\Large \color{purple}{\rightarrow x = x }\)

Infinite..

Answer 4

THIRD.
