Questions & Step-by-Step Solutions

What is the solution to the equation 7x + 2 = 3x + 18?
Correct Answer: 4
  • Step 1: Start with the equation 7x + 2 = 3x + 18.
  • Step 2: Subtract 3x from both sides to get 7x - 3x + 2 = 18.
  • Step 3: This simplifies to 4x + 2 = 18.
  • Step 4: Now, subtract 2 from both sides: 4x + 2 - 2 = 18 - 2.
  • Step 5: This simplifies to 4x = 16.
  • Step 6: Finally, divide both sides by 4 to solve for x: 4x / 4 = 16 / 4.
  • Step 7: This gives you x = 4.
