Evaluate the expression for the given value of the variable. \[ \frac{3(x+2)}{15 x-30} \text { for } x=4 \]

Step 1 ：Given the expression \(\frac{3(x+2)}{15x-30}\) and the value of x as 4.

Step 2 ：Substitute x=4 into the expression, we get \(\frac{3(4+2)}{15*4-30}\).

Step 3 ：Simplify the numerator, we get 18.

Step 4 ：Simplify the denominator, we get 30.

Step 5 ：Divide the numerator by the denominator, we get 0.6.

Step 6 ：Final Answer: The evaluated expression for x=4 is \(\boxed{0.6}\).
