This command works in CAS View only.

NSolutions[ <Equation> ]: Finds a numeric solution for a given equation for the variable x.; Example:
NSolutions[cos(x) = x] yields {0.7390851332151606}.

NSolutions[ <Equation>, <Variable> ]: Finds a numeric solution to an equation for a given unknown variable.; Example:
NSolutions[a^4 + 34a^3 - 34, a] yields {0.9904738886662206}.

NSolutions[ <Equation>, <Variable> ]: Finds a numeric solution to a set of equations for a given set of unknown variables.; Example:
NSolutions[{π / x = cos(x - 2y), 2 y - π = sin(x)}, {x=3, y=1.5}] yields {3.141592651686591, 1.570796327746508}.

Note: It is optional to give the starting point like {x=3, y=1.5}.
