I just realized I completely forgot the nonbasic math I learned in school. Can I solve this setup:

3x + 5y = ???

as it is or do I need more information?

Need more info

Seriously?

3x + 5y = 15xy

>> No.2962972

3x + 5y = ???

3x = ?^3 - 5y

x = ?^3 - 5y

>> No.2962973

For x:

x = (???-5y)/3

for y:

y = (???-3x)/5

for ???:

as stated
