This command works in CAS View only.

Solve[ <Equation> ]
Solves a given equation for the variable x and returns a list of all solutions.
Example:
Solve[x^2 = 4x] gives {x = 4, x = 0}, the solutions of x2 = 4x.
Solve[ <Equation>, <Variable> ]
Solves an equation for a given unknown variable and returns a list of all solutions.
Example:
Solve[x * a^2 = 4a] gives \{a = \frac{4}{x}\}, the solutions of Solve[x * a2 = 4a].
Solve[ <List of Equations>, <List of Variables> ]
Solves a set of equations for a given set of unknown variables and returns a list of all solutions.
Example:
Solve[{x = 4 x + y , y + x = 2}, {x, y}] yields (x = -1 y = 3), the sole solution of x = 4x + y and y + x = 2.
Example:
Solve[{2a^2+5a+3=b, a+b=3},{a,b}] yields {{a = 0, b = 3}, {a = -3, b = 6}}.
