On the second day, 2 times more wire was issued from the warehouse than on the first day

On the second day, 2 times more wire was issued from the warehouse than on the first day, and on the third day, 3 times more wire than on the first. How many kilograms of wire were given out in these three days, if on the first day they gave out 30 kg less than on the third?

Let x kg of wire be issued on the first day, then
2x kg. issued in the second
3 kg. issued in the third
Because on the third day they gave out 30 kg more than on the first, then we will make the equation
3x-x = 30
2x = 30
x = 15 kg. issued on the first day
2 * 15 = 30 kg. issued the second day
3 * 15 = 45 kg. issued on the third day
15 + 30 + 45 = 90kg. the wires were issued in these three days
