What is print 4*.__ -1 result=8 so, what's the number come in the space you can write only one number

Answer 1

Please write your question in a separate lines to can understand it and help you

Answer 2

#Equation solving using python:
'''suppose the unknown value is "x". So, 4*x - 1 = 8
Or, 4*x - 1 - 8 = 0
Or, 4*x - 9 = 0'''

from sympy.solvers import solve
from sympy import Symbol
x = Symbol('x')
print(solve(4*x - 9, x))

#Output: [9/4]

Answer 3

4 * x -1 = 8
4x -1 = 8
4x = 8 +1
4x = 9
x = 9/4= 2.25

Answer 4

MD. Ferdous Ibne Abu Bakar wow. This is great. Thank you.
I tried to solve the equations and this is what I got:

Although, both methods couldn't determine repeated root. So there will be no difference between x-1=0 and (x-1)*(x-1)=0 in code results.
Any ideas?

from sympy import *
x = Symbol('x')
eq = simplify((x+1)*(x+1))

x1 = solve(eq, x)

y = simplify((x+x1[0]))

print(f'{y} = 0')
