Questions & Step-by-Step Solutions

Solve for x: 7x - 3 = 18. (2023)
  • Step 1: Start with the equation 7x - 3 = 18.
  • Step 2: Add 3 to both sides of the equation to get rid of the -3. This gives you 7x = 18 + 3.
  • Step 3: Simplify the right side. 18 + 3 equals 21, so now you have 7x = 21.
  • Step 4: Now, divide both sides by 7 to solve for x. This gives you x = 21 / 7.
  • Step 5: Simplify 21 / 7. The answer is x = 3.
