use the row operations tool to solve the following system of equations, obtaining the solutions in fraction form.
15x + 13y + 4z = 8
11x + 13y + 9z = 1
3x + 5y + 7z = -5
8x + 8y + 2z = 6
7x + 5y + 2z = 2
give the values for x, y, and z with the fractions reduced to lowest terms (for example 1/2 rather than 3/6).
x =
y =
z =

Step-by-step explanation:

The matrix representation of the system of linear equations is:

First apply the following row operations:

The resulting matrix is:

Then apply  the row operations:

The resulting matrix is:

Now apply the row operations:

The resulting matrix is:

The equivalent linear system associated to this matrix is

To Solve this last system is very simple by substitution. The solutions are:
