Sure! Here is a simple Python program to calculate the arithmetic expression 5x + x5/5 + x:

# Input the value of x
x = float$input("Enterthevalueofx:")$
# Calculate the value of the expression
result = 5*x + x*5/5 + x
print$f"Theresultoftheexpression5\ast x+x\ast 5/5+xwherex=xis:result"$

You can run this program in any Python compiler or online Python compiler to calculate the value of the expression for any given value of x.
