Math Problem Statement

x-2-x+4

Solution

To simplify the expression x2x+4x - 2 - x + 4, let's combine like terms.

  1. Identify the like terms:

    • The terms with xx are xx and x-x.
    • The constant terms are 2-2 and +4+4.
  2. Combine the like terms: (xx)+(2+4)(x - x) + (-2 + 4)

  3. Simplify the expression: 0+2=20 + 2 = 2

Thus, the simplified form of the expression x2x+4x - 2 - x + 4 is 2.
