580 is the answer (now im using up my 20 digits lol)
-8x + y = 6
in the first equation, isolate y and then it becomes...
y = 6 + 8x
use this to replace the y in the second equation.
7x - 1y = -4
let y = 6 + 8x
7x - (6 + 8x) = -4
7x - 6 - 8x = -4
-x - 6 = -4
x + 6 = 4
x = 4 - 6
x = -2
now use this x = -2 into the equation with y.
y = 6 + 8x
y = 6 + 8(-2)
y = 6 -16
y = -10
Therefore, x = -2 and y = -10

Kilo is the unit prefix for multiplication by one thousand. Therefore, a kilogram, or kg, is equal to one thousand grams. To convert grams to kilograms, you simply have to multiply the number of kilograms to grams.
So, for example, if you had 16.24kg of a compound, it would equal:
Answer:
