4

To solve the equation 4b + 12 = 28, you first need to isolate the variable b. Start by eliminating the constant on the left side of the equation. To do this, subtract 12 from both sides:

4b + 12 - 12 = 28 - 12.

This simplifies to:

4b = 16.

Next, you need to solve for b by dividing both sides of the equation by 4:

4b / 4 = 16 / 4.

This results in:

b = 4.

The value of b is therefore 4, which is consistent with the understanding of basic algebraic manipulation. By isolating the variable through subtraction and then division, you determine the correct value that satisfies the original equation.
