Solve for x: 2x + 8 = 24
To solve this equation, you want to get the variable x on one side of the equation by itself. To do that, you will start by subtracting 8 from both sides of the equation, leaving you with 2x = 16. But we're not finished. The next step is to divide both sides of the equation by 2. That would give us x = 8.
