-k=287.658
divide by o
so k=0?
correct? thenk you
undefined not 0
If you're trying to find k, why divide by 0? You divide by the coefficient of k, which is -1.
-k/(-1) = 287.658/(-1)
k = -287.658
Or, to avoid any division at all, just swap sides of the = sign:
-k + k = 287.658 + k
0 = 287.68 + k
-287.658 = 287.658 + k - 287.658
-287.658 = k
You could probably have done that in your head, but I wanted to show the underlying machinery that makes it all happen.
To divide a number by zero is undefined in mathematics. It does not produce a valid answer. Therefore, you cannot divide 287.658 by zero.
In general, division is the operation of splitting a quantity or number into equal parts. When dividing by a non-zero number, the result is determined by how many times the divisor can be subtracted from the dividend. However, division by zero is not possible because it would involve dividing a quantity into an infinite number of equal parts, which is undefined.
