Answer 3

Solving the Equation 5 + 8x = 21

To solve the equation 5 + 8x = 21, we need to isolate the variable x. Here are the steps to solve it:

1. Subtract 5 from both sides of the equation: ``` 5 + 8x - 5 = 21 - 5 8x = 16 ```

2. Divide both sides of the equation by 8 to solve for x: ``` 8x/8 = 16/8 x = 2 ```

Therefore, the solution to the equation 5 + 8x = 21 is x = 2.
