Follow the full solution, then compare it with the other examples linked below.

Example 1

easy
Show that x+1=x+3x + 1 = x + 3 is a contradiction.

Solution

  1. 1
    Step 1: Subtract xx from both sides: 1=31 = 3.
  2. 2
    Step 2: 1โ‰ 31 \neq 3. This is always false.
  3. 3
    Step 3: No value of xx can make this true โ€” it's a contradiction.

Answer

Contradiction โ€” no solution.
