artys height is 63 in. artys height is 3 inches less than 3 times his younger brother julians height. what is julians height in jnches
Let's assume Julian's height is x inches.
According to the given information, Arty's height is 63 inches.
We also know that Arty's height is 3 inches less than 3 times Julian's height.
So, 63 = 3x - 3.
Adding 3 to both sides of the equation, we have: 63 + 3 = 3x.
63 + 3 = 66.
Therefore, 3x = 66.
Dividing both sides of the equation by 3, we get: x = 22.
So, Julian's height is 22 inches. Answer: \boxed{22}.
