Add one to a number, then double the sum, and you get 56.

how do i solve it and write it as a equation

(x+1)*2=56

1. divide both sides by 2
2. subtract 1 from both sides

you get x=27

For all of these questions just remember that when they say "a number" you should think of a variable like x or y. And when they say add you use a plus sign +, when they say difference use a - sign. When they say double its multiplication, etc.

That's correct! To solve the problem, you can create an equation based on the information given. Let's break it down step-by-step:

1. Start with "Add one to a number". So, let's assume the number is x. Adding one to x gives us x + 1.

2. Next, "double the sum". This means we need to multiply the sum by 2. So, we get (x + 1) * 2.

3. Finally, we are told that the result is 56. So, the equation becomes: (x + 1) * 2 = 56.

Now that we have the equation (x + 1) * 2 = 56, we can solve it to find the value of x.

1. Divide both sides of the equation by 2 to isolate the expression (x + 1): ((x + 1) * 2) / 2 = 56 / 2.

Simplifying the equation: (x + 1) = 28.

2. Subtract 1 from both sides of the equation to isolate x: (x + 1) - 1 = 28 - 1.

Simplifying the equation: x = 27.

Therefore, the solution to the problem is x = 27.
