Final answer:
The solution to the equation x + 4/5 = x is all real numbers.
Step-by-step explanation:
To solve for x in the equation x + 4/5 = x, we can start by subtracting x from both sides of the equation. This gives us 4/5 = 0. Since 4/5 is equal to 0, the equation is true for any value of x.
Therefore, the solution to the equation is all real numbers.
