We know that Griffin is 61 inches tall.
We also know that Grayson is 2 inches taller than Griffin, which means Grayson is 61 + 2 = 63 inches tall.
Gracie is x inches shorter than Grayson, so Gracie's height is 63 - x inches.
We are given that Gracie's height is 56 inches, so we can write: 63 - x = 56.
Solving for x, we get: x = 7.
The value of x is 7.
#### 7
The answer is: 7
