Here are the matches for the one variable equations based on their descriptions:

  1. x−7=7−x: Infinite solutions (This equation simplifies to 0=0, meaning it's true for all x)

  2. 3(x+5)=3x+5: One solution (This simplifies to 15=15, which is another identity)

  3. 10−x=25: One solution (This can be solved to find x = -15)

  4. 2(x+4)=2x+5+3: No solution (This simplifies to 8=8, which is not true)

So,

  • x−7=7−x: Infinite solutions
  • 3(x+5)=3x+5: One solution
  • 10−x=25: One solution
  • 2(x+4)=2x+5+3: No solution
