I add 7 to a certain number. I double the result. My final answer is 34what was my number
Let's break down the problem step by step:
First, you added 7 to a certain number, which we'll call "x". So, we have: x + 7.
Next, you doubled the result of the previous step. So, we have: 2(x + 7).
According to the problem, the final answer is 34. So, we have the equation: 2(x + 7) = 34.
To find the value of x, we need to solve this equation. We can do that by simplifying and isolating x.
First, distribute the 2 on the left-hand side of the equation: 2x + 14 = 34.
Next, subtract 14 from both sides of the equation to isolate 2x: 2x = 34 - 14, which simplifies to 2x = 20.
Finally, divide both sides of the equation by 2 to solve for x: x = 20 / 2, which simplifies to x = 10.
Therefore, your original number was 10.
