Questions & Step-by-Step Solutions

If 9x - 4 = 5, what is x?
  • Step 1: Start with the equation 9x - 4 = 5.
  • Step 2: Add 4 to both sides of the equation to get rid of the -4. This gives you 9x = 5 + 4.
  • Step 3: Simplify the right side. 5 + 4 equals 9, so now you have 9x = 9.
  • Step 4: Now, divide both sides of the equation by 9 to solve for x. This gives you x = 9 / 9.
  • Step 5: Simplify the right side. 9 divided by 9 equals 1, so x = 1.
