If 4x = 28, what is the value of x?

To find the value of x in the equation 4x = 28, we need to isolate x. This is done by dividing both sides of the equation by 4.

When you divide 28 by 4, you get:

28 ÷ 4 = 7.

So, x equals 7.

This process demonstrates basic algebraic manipulation, where we rearrange the equation to solve for the variable. In this case, the correct value of x is indeed 7, confirming that option B is accurate.
