1 KG = .001 metric tons. Move the decimal point over three to make it 48.567 metric tons.
Answer:
Here,

substituting the value of 4y in eqn i fron eqn ii
so eqn i becomes

So

Thus,

...hope this helps:)
from the given equation
X+Y=20-->i
X-Y=14--->ii
add eq i and eq ii
2x=34
x=17
putting the value of x=17 in eq i
17+y=20
then y = 3 so the right answer is
17 and 3
