correct :)

k

amistre64 · Answer

[9x + 3y - 6z = 18]/18

x/2 + y/6 - z/3 = 1
 2    ,   6   ,  -3

anonymous · Answer

do you always divide by the end number?

amistre64 · Answer

it might be easier to see the negatives if you attach them to the bottoms like this:

  x        y        z
--- + --- + --- = 1
  2        6      -3

amistre64 · Answer

It is one method in finding out the intercepts of an equation.

amistre64 · Answer

a more popular method is simply to zero out the other variable and solve for the one thats left

anonymous · Answer

the one with zero u add it to the space where the variable is?

amistre64 · Answer

yes, for example, to find the z intercept:

9(0) + 3(0) - 6z = 18

0+0 -6z = 18

-6z = 18

z = 18/-6 = -3

anonymous · Answer

can you write a example problem down and I try to solve it and you tell me if it's right?

amistre64 · Answer

4x -5y -10z = 20

anonymous · Answer

5, -4, -2 is that right?

amistre64 · Answer

that is correct :)

anonymous · Answer

wow thank you I was stuck on this for like a day
