How do you solve x + 5 = 2x?

To solve the equation x + 5 = 2x, follow these steps:

Step 1: Isolate the variable

First, you want to get all the terms involving x on one side of the equation. You can do this by subtracting x from both sides:

• x + 5 - x = 2x - x

This simplifies to:

• 5 = x

Step 2: Write the solution

The solution to the equation is:

• x = 5

Verification

To ensure the solution is correct, substitute x = 5 back into the original equation:

• 5 + 5 = 2(5)
• 10 = 10

Since both sides are equal, the solution is verified.
