Answer:
The augmented matrix for each set of linear equations is:
a)
Augmented matrix:
b)
Augmented matrix:
c)
Augmented matrix:
d)
Augmented matrix:
Step-by-step explanation:
In order to find the augmented matrix, you have to take the numeric values of each variable and make a matrix with them. For example, in the linear system a) you can make a matrix out of the numeric values accompanying x_1 and x_2, this matrix will be:
Then you have to make a vector with the constants in the linear equations, for the case of system a) the vector will be:
To construct the augmented matrix, you append those matrices together and create a new one:
