it is 7-4
what is the answer to this problem 2(4 - 2x + y) - 4(5 + x - y)
If you have x+-y=z, than you can turrn it into subtraction: x-y=z. x+-y=x-y
substitute 0 for y and solve for x. then substitute x for 0 and solve for why and you have the x and y coordinates
!x-y! first calculate x-y, then calculate av.
A graph has both an x and y axis.
If you mean: y = -1-x then the straight line equation can be expressed as x+y+1 = 0
Supplement of an angle measure x* be y*=(180-x*). Or x+y=180* for the problem x=9y => x+y = 9y+y=10y=180 => y=18* and x =172*
If you mean: y = x-2 and y = 2x-8 then it works out that x = 6 and y = 4
X = Y = 9 The answer must be 9, since it says it in the problem. x = 9, y=9, and x = y are all true based on the given info.
In your case, there are two possibilities: x-3=y or x/2=y. In the first case, y=7. In the second case, y=5. Make sure you address this problem with your teacher.
y=2x+9 and y=x+6
The question is not altogether clear, but in a question such as What is x% of y? (where x and y are numbers), y is the original value. Incidentally, since x% of y is the same as y% of x, it does not matter all that much.
