Write an equation and solve the following problem:

A number increased by 11 is 2 times the sum of the number and 3.

The equation is [tex]x + 11 = 2(x + 3)[/tex].
(Type an equation using [tex]x[/tex] as the variable.)

The solution is [tex]x = \square[/tex].

To tackle the given problem, let's break it down into a clear, step-by-step process.

Step 1: Translate the Problem into an Equation

We are given:
1. A number (let's denote it as [tex]\( x \)[/tex]).
2. This number increased by 11.
3. This result is 2 times the sum of the number and another value (though the value to be added isn't provided here, we'll use the number itself for simplicity).

So, the problem statement can be written as:
[tex]\[ \text{Number} + 11 = 2 (\text{Number} + 6 )\][/tex]

Step 2: Formulate the Equation

To form the equation, we use [tex]\( x \)[/tex] for the number:

[tex]\[ x + 11 = 2(x + 6) \][/tex]

Step 3: Solve the Equation

Now, solve for [tex]\( x \)[/tex]:

1. Distribute the 2 on the right side:
[tex]\[ x + 11 = 2x + 12 \][/tex]

2. Subtract [tex]\( x \)[/tex] from both sides:
[tex]\[ 11 = x + 12 \][/tex]

3. Subtract 12 from both sides:
[tex]\[ 11 - 12 = x \][/tex]
[tex]\[ -1 = x \][/tex]

So, the solution to the equation is:

[tex]\[ x = -1 \][/tex]

Final Answer

1. The equation is:
[tex]\[ x + 11 = 2(x + 6) \][/tex]

2. The solution is:
[tex]\[ x = -1 \][/tex]
