Questions & Step-by-Step Solutions

What is the value of x in the equation 2x - 4 = 10?
Correct Answer: 7
  • Step 1: Start with the equation 2x - 4 = 10.
  • Step 2: Add 4 to both sides of the equation to get rid of the -4. This gives you 2x = 10 + 4.
  • Step 3: Simplify the right side. 10 + 4 equals 14, so now you have 2x = 14.
  • Step 4: Now, divide both sides of the equation by 2 to solve for x. This means you do 14 divided by 2.
  • Step 5: Calculate 14 divided by 2, which equals 7. So, x = 7.
