Solve the equation. \[ 6[1-(-5 x-5)]=240 x+246 \]

Step 1 ：First, distribute the 6 inside the brackets on the left side of the equation to get \(30x + 30 = 240x + 246\).

Step 2 ：Next, move all terms involving x to one side of the equation and the constant terms to the other side to get \(210x = -216\).

Step 3 ：Finally, solve for x by dividing both sides by 210 to get \(x = -1\).

Step 4 ：Substitute x = -1 into the original equation to verify the solution. Both sides of the equation are equal, confirming that the solution is correct.

Step 5 ：Final Answer: The solution to the equation is \(\boxed{-1}\).
