What is the solution for y in the equation 3y + 9 = 0?

Explanation:
To solve the equation 3y + 9 = 0 for y, you start by isolating the term containing y. First, subtract 9 from both sides of the equation: 3y + 9 - 9 = 0 - 9 This simplifies to: 3y = -9 Next, to solve for y, divide both sides of the equation by 3: 3y / 3 = -9 / 3 This results in: y = -3 Therefore, the solution for y is -3. This shows that by following the correct steps of rearranging and isolating the variable, you arrive at the correct answer. The other options do not satisfy the original equation when substituted back in, further confirming that the calculated solution is the only one that is correct.

3y + 9 - 9 = 0 - 9

This simplifies to:

3y = -9

Next, to solve for y, divide both sides of the equation by 3:

3y / 3 = -9 / 3

This results in:

y = -3

Therefore, the solution for y is -3. This shows that by following the correct steps of rearranging and isolating the variable, you arrive at the correct answer.
