Solve for \( y \) \[ 6 y+3(y+3)=-36 \]

To solve for \( y \), we start by simplifying the equation step-by-step. First, distribute the \( 3 \) in the expression \( 3(y + 3) \): \[ 6y + 3y + 9 = -36 \] Now, combine like terms: \[ 9y + 9 = -36 \] Next, isolate the term with \( y \) by subtracting \( 9 \) from both sides: \[ 9y = -36 - 9 \] \[ 9y = -45 \] Now, divide both sides by \( 9 \) to solve for \( y \): \[ y = \frac{-45}{9} \] \[ y = -5 \] So, the solution is: \[ y = -5 \]
