X+3/16=9/16

To solve the equation \( \frac{x + 3}{16} = \frac{9}{16} \), follow these steps:

1. Eliminate the denominator: Multiply both sides of the equation by 16 to get rid of the fraction:

   \[ x + 3 = 9 \]

2. Isolate \( x \): Subtract 3 from both sides:

   \[ x = 9 - 3 \]

   \[ x = 6 \]

Thus, the solution is \( x = 6 \).
