Chapter 2: Problem 13

Let \(x\) represent the number. Use the given conditions to write an equation. Solve the equation and find the number. A number increased by 5 is two times the number. Find the number.

Short Answer

Expert verified
The number we are looking for is 5.

Step by step solution

01

Formulate the equation

If \(x\) is the number, 'a number increased by 5' can be written as \(x + 5\), and 'two times the number' can be written as \(2x\). The equation that represents the condition is \(x + 5 = 2x\).
02

Solve for x

To solve for \(x\), we can subtract \(x\) from both sides of the equation. This gives us \(5 = x\).
