-x on both sides to get
x=15
5*2x is 10x
5*3y is 15y
5*5z is 25z
There is 17 Ounces left! Or 2.12500 cups.
4y+2x=14 ==> multiply this 1st equation by (-1) => -4y-2x=-14
Now add it up to the 2nd equation
-4y-2x=-14
2y+2x=10
-------------- And now add them up
-2y +0x=-4
==> -2y=-4==> 2y = 4 & y=2
Last step: plug y into any equation & you will find x=3
Answer:
The three-dimensional surface represented by the equation x+y=2 is an inclined plane, as seen in the image.
