Impossible. You need a minimum of 3 equations, or two given variables.
OpenStudy (anonymous):
there's more.. I need to find the n-vector form
OpenStudy (anonymous):
x __ __ __
y = __ + __ s + __ t
z __ __ __

@saifoo.khan can you help me please?
OpenStudy (anonymous):
2x-3y-5z=-16
x+3y+5z-16/2=1 1/2y+2 1/2z-8
that what my calculator said.

OpenStudy (anonymous):
ok it is simple
OpenStudy (anonymous):
first of all solve for x then for y then for z
OpenStudy (anonymous):
i will show you how

you can't solve for x,y,z unless you have more
equations..
OpenStudy (anonymous):
wait and you will see
OpenStudy (anonymous):
2x-3y-5z=-16
OpenStudy (anonymous):
step one: 2x = 3y + 5z =16
OpenStudy (anonymous):
step two: \[x = \frac{ 3 }{ 2 }y + \frac{ 5 }{2 }z -8\]

\[x = 1.5y + 2.5z -8\]
OpenStudy (anonymous):
are you following
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
so this is your value of x
OpenStudy (anonymous):
now i will solve for y if you want?
