Solve for x in the equation 2x + 5 = 13.
To solve this equation, we want to isolate the variable x on one side of the equation. We can do this by performing inverse operations.
Step 1: Subtract 5 from both sides of the equation: 2x + 5 - 5 = 13 - 5 2x = 8
Step 2: Divide both sides of the equation by 2: (2x) / 2 = 8 / 2 x = 4
Therefore, the solution to the equation 2x + 5 = 13 is x = 4.
