1. The problem statement, all variables and given/known data Solve: -8x-5y-9z=4 3. The attempt at a solution I just need to know if I'm doing this correctly... There is only one equation given, so I expressed x in terms of y and z and got: x=-5/8y-9/8z-1/2 then I set y=s and z=t x=-(5/8)s -(9/8)t -1/2 so I'd enter the answers as: x = -(5/8)s-(9/8)t-1/2 y = s z = t Is that correct? I only have one attempt for the online assignment. Thanks!
