4x -3y + 2 + 112x + y - 4z = -1x + 2y -2z = 1

Question

Whats the answer. I have huge numbers for solutions

 

Answer 1

Khalid,

What if you rewrote it like this:

         116x - 2y - 4z + 2 = 1

 +       - 1x +2y - 2z + 0 = 1

-----------------------------

the best you can do is simplify the answer as z(x)

I don't want to cheat and give you the answer, but it will look like this below:

z(x) = (a number)x + (another number)

Once you find this for one of the equations, you can replace the z in the other equation with (a number)x + (another number) and then you can simultaneously solve for the z and x solutions.  Knowing z and x, you can isolate to solve for y.
