Answer: 62

Step-by-step explanation: Set up your equation

  1. 21+x=2x-41 because the number (x) that 21 is added to is 41 less than (so subtraction) twice (so multiply the number x by 2) the number (x).
  2. Get the x's on one side by subtracting the single x
  3. 21=x-41
  4. Now add 41 to both sides to completely isolate x
  5. 62=x
  6. So, your answer is x=62. The number is 62.

Check your work. 62+21=83. 2(62)= 124. 124-41=83. Both equations equal 83, so the solution is correct.
