Hello!
Answer:

Explanation:
→ We want to find how many solutions this equation has:

◼ Subtract x from both sides:

◼ Simplify both sides:

→ The equation is a contradiction, so it has no solution.
So the answer to the question "How many solutions does this equation have?" is 0.
Conclusion:
The equation x=x+2 has no solution.
The answer of the question is 0.
