I would go about solving this by elimination because the x variables are already the same so all you would have to do is change one equation to the opposite signs and add them, so it would look like:
7y + 5x = 19
+ -3y - 5x = -7
-------------------
4y=12
y=3
Semi-monthly means twice every month, typically either on the 1st and 15th,
or on the 15th and last.
Months don't line up with weeks in any regular way. Depending on the
company, if they say "bi-monthly", they may pay 24 times a year, or else
26 times a year.
If they pay every 2 weeks, the semi-monthly is $2400.
10 hope this helps good luck
