Questions & Step-by-Step Solutions

The difference between a number and 7 is 5. What is the number?
  • Step 1: Understand the question. We need to find a number that, when you subtract 7 from it, the result is 5.
  • Step 2: Let the unknown number be represented by 'x'.
  • Step 3: Write the equation based on the question: x - 7 = 5.
  • Step 4: To solve for x, we need to get rid of the -7. We can do this by adding 7 to both sides of the equation.
  • Step 5: After adding 7 to both sides, the equation becomes: x - 7 + 7 = 5 + 7.
  • Step 6: Simplify both sides: x = 12.
  • Step 7: The number we are looking for is 12.
