write a matrix for x-y=8,-2x-5y-6z=-27, 9x+10y-z=54

ok

[ 1 -1 0 8]
[-2 -5 -6 -27]
[9 10 -1 54]

its supposed to be in one matricies but there is no button on the computer for that!!

To write the matrix for the given system of equations:

x - y = 8
-2x - 5y - 6z = -27
9x + 10y - z = 54

We will create a matrix where each equation corresponds to a row and each variable corresponds to a column. The coefficients of the variables will be placed in the respective columns, and the constants on the right side of the equations will be added as an additional column.

The matrix representation of the system can be written as:

[ 1 -1 0 | 8 ]
[ -2 -5 -6 | -27 ]
[ 9 10 -1 | 54 ]

Here, the first column represents the coefficients of the variable 'x' in each equation, the second column represents the coefficients of 'y', the third column represents the coefficients of 'z', and the rightmost column represents the constants on the right side of each equation.
