Let's translate the words into an equation step by step.
1. "twice a number" can be represented as \(2x\), where \(x\) is the number.
2. "plus 7" means we add 7 to the expression above, resulting in \(2x + 7\).
3. "is 23" means we set the equation equal to 23.
Putting it all together, we get the equation:
\[
2x + 7 = 23
\]
Now, let's solve the equation:
1. Subtract 7 from both sides:
\[
2x + 7 - 7 = 23 - 7
\]
This simplifies to:
\[
2x = 16
\]
2. Now, divide both sides by 2:
\[
x = \frac{16}{2}
\]
This simplifies to:
\[
x = 8
\]
So, the solution to the equation is:
\[
x = 8
\]
