Answer:

Infinite amount of solutions.

Step-by-step explanation:

Step 1: Write equation

2x - x + 7 = x + 3 + 4

Step 2: Solve for x

  1. Combine like terms: x + 7 = x + 7
  2. Subtract 7 on both sides: x = x

Here, we see that x is infinite amount of solution. We can plug in any number x and it will render the equation true.
