Did I solve this correctly? No calculus in 7 years.

[Guest]

Hello been out of advanced placement calculus for 7 years. It was my favorite math class by far throughout all of school. Made an A+. I didn't get to attend college due ro family issues but have always wanted to go back or take refreshers in calculus. So I was just sitting here and made up a multi-variable equation. Did I solve the differential correct? Is the problem even possible? I know I can just look up an equation but I just wanted to see how much I retained first. Thank you.

I'm sorry but that is impossible to read. It is sideways and much too dark. Can't you type the problem?
