Answer:
3 loaves of bread
Step-by-step explanation:
We must divide 
by 
and take an integer part of this dividing.
The integer part of a mixed fraction 
is 3, and this is the answer.
by the use of elimination method
make all coefficients of subject to be eliminated similar..by multiplying the coefficients with one another
for eqn(i)
5(-10y+9x=-9)
-50y+45x=-45
for eqn(ii)
9(10y+5x=-5)
90y+45x=-45
-50y+45x=-45
90y+45x=-45
...subtract each set from the other...
we get
-140y+0=0
y=0
from eqn(i)
10y+5x=-5
0+5x=-5
x= -1
I don’t understand if this is a math problem or a statement.
