How do you solve for x in the equation 3x + 4 = 10?

To solve for x in the equation 3x + 4 = 10, the first step is to isolate the term that contains x. This can be accomplished by subtracting 4 from both sides of the equation. This gives:

3x + 4 - 4 = 10 - 4, which simplifies to 3x = 6.

Next, to solve for x, you need to divide both sides by 3. This produces the equation:

x = 6 / 3, which simplifies to x = 2.

Thus, the solution to the equation, which represents the value of x that makes the original equation true, is 2. This means that option B is the correct answer, as it accurately reflects the solution derived from the given equation.
