Answer:
Required unique solutions are 8, 4, 0 and the system is consistant.
Step-by-step explanation:
Given system of equation,
5x-2y+4z=12
x+y+z=8
4x-3y+3z=4
To find solution of the system re-write as,
Hence solutions are 8, 4 and 0. And it is a unique solution. Therefore system is consistent.
This uses the concept of proportions.
.002 converted to a fraction is 2/1000, or 1/500.
We set up the proportion like so:
10/100 = .002/x
Solve for x.
Cross-multiply.
10 * x = .002 * 100
10 * x = .2
x = .2 / 10
x = .02
The answer is .02
