Final answer:
To find the general solutions of the systems, perform row operations on the augmented matrices to reduce them to row echelon form or reduced row echelon form. This will simplify the coefficients and allow us to determine the values of the variables. Express the solutions in terms of the general form.
Step-by-step explanation:
To find the general solutions of the systems, we need to solve the augmented matrices by performing row operations. The row operations include swapping rows, multiplying rows by constants, and adding or subtracting rows. By applying these operations, we can reduce the matrices to row echelon form or reduced row echelon form. The resulting system will represent the equations of the original system, but with simplified coefficients. From there, we can determine the variables' values and express the general solutions.
