\(\large{\frac72x-\frac12y=\frac92}\)
If you want to get rid of fractions you can multiply by a common denominator, in this case it is 2
\(\large\color{red}{2(}{\frac72x-\frac12y=\frac92}\color{red}{)}\\
~\\
=> ~7x-1y=9\)

both y are negative
notdude:
Right so we need to multiply one of the equations by a negative to get a positive
notdude:
\(7x-y=9\)
or
\(3x-y=5\)
notdude:
Choose one to multiply by a negative

first

Correction: \(3(1)-y=5\)
