Alright, you have one common term in both, that is 6x. So you can subtract.

Answer 4

b

Answer 5

\(\Large \color{purple}{\rightarrow 4y = 12 }\)
\(\Large \color{purple}{\rightarrow y = 3 }\)

\(\Large \color{purple}{\rightarrow 6x - 3 = 33 }\)
\(\Large \color{purple}{\rightarrow 6x = 36 }\)
\(\Large \color{purple}{\rightarrow x = 6 }\)

(6,3) is what you get.
