Answer:

Step-by-step explanation:
Notice that in the second equation, the coefficient of
is
times greater than in the first. Therefore, by making the coefficient of
in the second equation
times greater than in the first, it's impossible to only isolate one variable.
Therefore, when
, there are no solutions to this system.
4 loaves : 6 cups
That simplifies to 2 loaves : 3 cups
So, your ratio is 2:3
=(3a-4a-3a)+(2b+6b-2b)+(-7c+9c-7c)
=-4a+6b-5c #
The area is 270 inches, because you would do length times width, which in this situation is 28 and 15. You multiply them, and you get 270.
36/48 do the math and you will get some thing similer
