This command works in CAS View only.
- Solutions[ <Equation> ]
- Solves a given equation (or a set of equations) for the variable x and returns a list of all solutions.
- Example:
Solutions[x^2 = 4x]
gives {{4}, {0}}, the solutions of x2 = 4x.
- Solutions[ <Equation>, <Variable> ]
- Solves an equation (or a set of equations) for a given unknown variable (or set of variables) and returns a list of all solutions.
- Example:
Solutions[{x = 4 x + y , y + x = 2}, {x, y}]
gives { {-1, 3} }, the sole solution of x = 4x + y and y + x = 2.
