Questions & Step-by-Step Solutions

What is the value of x in the equation 3x - 7 = 2?
  • Step 1: Start with the equation 3x - 7 = 2.
  • Step 2: To get rid of the -7, add 7 to both sides of the equation.
  • Step 3: The equation now looks like this: 3x = 2 + 7.
  • Step 4: Simplify the right side: 2 + 7 equals 9, so now we have 3x = 9.
  • Step 5: Now, to find x, divide both sides of the equation by 3.
  • Step 6: The equation now looks like this: x = 9 / 3.
  • Step 7: Simplify the right side: 9 divided by 3 equals 3.
  • Step 8: Therefore, the value of x is 3.
