import sympy as sy x1, x2 = sy.symbols("x1 x2") equations = [ sy.Eq( 2*x1 + 1*x2 , 10 ), sy.Eq( 1*x1 - 2*x2 , 11 ) ] print sy.solve(equations) # Result: {x1: 31/5, x2: -12/5}

import sympy as sy x, y = sy.symbols("x y") # nsolve needs the (in this case: two) equations, the names of the variables # (x,y) we try to evaluate solutions for, and an initial guess (1,1) for the # solution print sy.nsolve((x**3+sy.exp(y)-4,x+3*y),(x,y),(1,1)) The result s...

import sympy as sy # Symbols have to be defined before one can use them x = sy.S('x') # Definition of the equation to be solved eq=sy.Eq(x**2 + 2, 6) #Print the solution of the equation print sy.solve(eq) The result printed will be: [-2, 2]
