Questions & Step-by-Step Solutions

What is the value of x if 3x - 5 = 16?
Correct Answer: 7
  • Step 1: Start with the equation 3x - 5 = 16.
  • Step 2: Add 5 to both sides of the equation to get rid of -5. This gives you 3x = 16 + 5.
  • Step 3: Calculate 16 + 5, which equals 21. Now the equation is 3x = 21.
  • Step 4: Divide both sides of the equation by 3 to solve for x. This gives you x = 21 / 3.
  • Step 5: Calculate 21 divided by 3, which equals 7. So, x = 7.
