Answer:
<em>Their masses are 100 kg and 90 kg</em>
Step-by-step explanation:
<u>Equations</u>
We'll solve the problem by setting only one variable. Let's call:
x = weight of the heavier boxer
Since the sum of the masses of both boxers is 190 Kg:
190 - x = mass of the lighter boxer.
It's given that 
of the mass of the heavier boxer is 10 kg less than the mass of the other, thus:
Operating:
Multiplying by 5:
Simplifying:
The heavier boxer's mass is 100 kg. The lighter boxer has a mass of 190-100 = 90 kg.
Their masses are 100 kg and 90 kg
<span>a line crosses the x axis when y = 0
0 = -3x - 18
Add 3x to both sides
3x = -18
Divide both sides by 3
x = -6
Graph intersects x axis at point
(-6, 0)

Since one ton is 2000 pounds, 2.25 tons is equal to 4500 pounds. Now do
4500-2150=2350
So he can carry 2350 more pounds
