Answer:
[tex](x=0.8,y=0.2,z=-0.7)[/tex]
Step-by-step explanation:
The given system of equations is:
[tex]1.6x+2.4y-3.2z=4.1\\5.1x-6.3y+0.6z=2.3\\4.2x+3.5y+4.9z=0.7[/tex]
Using technology, we obtain the exact solutions as:
[tex](x=\frac{28727}{35496},y=\frac{7897}{35496},z=\frac{25193}{35496})[/tex]
We now now need convert to decimals and round to 1 decimal place to get:
[tex](x=0.8,y=0.2,z=-0.7)[/tex]
