Final answer:
The augmented matrix for the given system is [2 1 | 7] [4 -5 | 2].
Step-by-step explanation:
In order to convert the system of equations to an augmented matrix, we need to organize the coefficients of the variables into a matrix and add the constants on the right side.
The augmented matrix for the given system is:
[2 1 | 7]
[4 -5 | 2]
