Question

Use technology to solve the system of equations. Express all solutions as decimals, rounded to one decimal place. 1.6x + 2.4y − 3.2z = 4.1 5.1x − 6.3y + 0.6z = 2.3 4.2x + 3.5y + 4.9z = 0.7

Answer 1

Answer:

$(x=0.8,y=0.2,z=-0.7)$

Step-by-step explanation:

The given system of equations is:

$1.6x+2.4y-3.2z=4.1\\5.1x-6.3y+0.6z=2.3\\4.2x+3.5y+4.9z=0.7$

Using technology, we obtain the exact solutions as:

$(x=\frac{28727}{35496},y=\frac{7897}{35496},z=\frac{25193}{35496})$

We now now need convert to decimals and round to 1 decimal place to get:

$(x=0.8,y=0.2,z=-0.7)$
