[Jawaban] Provide a step-by-step solution for the equation: \[ 3y + 5.2 = 2 - 5y \] 1. Add \(5y\) to both sides of the equation to eliminate \(-5y\) on the right: \[ 3y + 5y + 5.2 = 2 \] 2. Simplify the equation: \[ 8y + 5.2 = 2 \] 3. Subtract \(5.2\) from both sides to isolate the term with \(y\): \[ 8y = 2 - 5.2 \] 4. Calculate the right-hand side: \[ 8y = -3.2 \] 5. Divide both sides by 8 to solve for \(y\): \[ y = \frac{-3.2}{8} \] 6. Simplify the result: \[ y = -0.4 \] Therefore, the solution is \( y = -0.4 \).
