If 4(x - 3) = 28, what is the value of x?

To solve the equation 4(x - 3) = 28, start by dividing both sides by 4. This simplifies the equation to:

x - 3 = 7

Next, isolate the variable x by adding 3 to both sides:

x = 7 + 3

Thus, x = 10.

This shows that the correct value of x is 10, making it the solution to the equation. The steps taken demonstrate the process of isolating x through basic algebraic operations, providing a clear path to the correct answer.
