I'm not sure. Can you give me a hint?
ganeshie8 (ganeshie8):
look at the third equation; it looks simpler as it has only two variables. maybe start by isolating \(z\) |dw:1446478684418:dw|
OpenStudy (liv1234):
So, we could start by solving for z?
ganeshie8 (ganeshie8):
what do you get when you isolate \(z\) ?
OpenStudy (liv1234):
2z?
