Solve for y in the equation 4y + 6 = 30.

The correct answer is: 6

To solve the equation 4y + 6 = 30 for y, you start by isolating the variable on one side of the equation. First, subtract 6 from both sides to eliminate the constant term: 4y + 6 - 6 = 30 - 6 This simplifies to: 4y = 24 Next, divide both sides by 4 to solve for y: 4y / 4 = 24 / 4 This results in: y = 6 Thus, the correct value of y is 6, meaning option B is indeed correct. The calculations show that y was successfully isolated, confirming that the process of simplifying and isolating the variable was followed accurately.
