х+4х=640 
5х=640 
х=640/5 
х=128 - рублей стоит рубашка 
128*4=512 - рублей стоит галстук

Solution for Finding the Cost of the Tie

To find the cost of the tie, we can use the given information that the shirt is 4 times more expensive than the tie. Let's break down the steps to find the cost of the tie.

1. Let's assume the cost of the tie as 'x' rubles. 2. Given that the shirt is 4 times more expensive than the tie, the cost of the shirt would be 4x rubles. 3. According to the given information, the total cost of the shirt and tie is 640 rubles. So, we can form the equation: x + 4x = 640. 4. Solving the equation: - 5x = 640 - x = 640 / 5 - x = 128

Therefore, the cost of the tie is 128 rubles.
