Solve for the value f y in the equation 2y - 9 = 11

Answer 1

To solve the equation \( 2y - 9 = 11 \), follow these steps:

1. Add 9 to both sides of the equation: \[ 2y - 9 + 9 = 11 + 9 \] Simplifying, we get: \[ 2y = 20 \]

2. Next, divide both sides by 2: \[ \frac{2y}{2} = \frac{20}{2} \] Simplifying gives us: \[ y = 10 \]

Thus, the value of \( y \) is \( 10 \).
