Python – How to resolve the “Absolute values cannot be inverted in the complex domain” error in sympy

I have the following equation:

Eq(5*Abs(4*x+2)+6,56). 

What I want to do is solve x = -3 math problem 5 |4x+2|+6=56, but I keep getting it

“Absolute values cannot be inverted in the complex domain”

Sympathize with mistakes.

Is there a solution?

You must specify that x is a real-valued variable. You can do this when you define a variable as follows.

import sympy as sp
x = sp.symbols('x', real = True)
eq = sp. Eq(5*sp. Abs(4*x+2)+6,56)
sol = sp.solve(eq, x)
print(sol)

[-3, 2]

Edit: You can use the sympy.solveset function instead of sympy.solve. In this case, you need to explicitly state that you are solving a field of real numbers. By doing this, you do not have to define the variable as a real variable.

import sympy as sp
x = sp.symbols('x') # implies that x is complex
eq = sp. Eq(5*sp. Abs(4*x+2)+6,56)
sol = sp.solveset(eq, x, domain=sp. S.Reals)
print(sol)

{-3, 2}
