3^2+y+8[(x+2y^2=a-z)+2x^3+(-2z=2.4)+10y-5z^3=k=9x

Question

I need help solving this. Thank you.

Answer 1

This is gibberish.

For example, (x+2y^2 = a-z) is a separate equation, not something to include inside parentheses within an equation.

There's no closing bracket (the 8[ part).

We'd like to help, but we can't tell what you're asking.
