Answer:
Infinitely many solutions
Explanation:
5-x= -(x - 5) ➡ 5 - x = -x + 5 add x to both sides and subtract 5 from both sides
5 - x - 5 + x = -x + x - 5 + 5 ➡0 = 0 in this case we say the equation has infinitely many solutions because whatever value you give for x there will always be a solution.
