We can write it down as:
Jill = x Ned = 1,5 * x Tom = x + 15
So:
190 = x + 1,5 * x + x + 15 190 = x + 1,5x + x + 15 190 = 2x + 1,5x + 15 190 = 3,5x + 15 / - 15 (both sides) 175 = 3,5x / ÷ 3,5 (both sides) x = 50
So:
Jill = 50 kg Ned = 1,5 * 50 = 75 kg Tom = 50 + 15 = 65 kg
Jill weighs 50 kg, Ned weighs 75 kg, and Tom weighs 65 kg. The weights were calculated using a system of equations based on their relationships. The total weight of all three adds up to 190 kg.
