Those are linear. Do you mean "inequalities".

Anyway, solve the Equality and decide which side of the intersection counts. Of course, you must also decide if the intersection itself counts.

Lets assume you mean:

\(\displaystyle x^2+y=37\)
\(\displaystyle x-y^2=5\)
\(\displaystyle x+y+z=3\)

This is a system of equations. In plain ASCII we use "^" to denote a power.
