![3x_{1}+ x_{2}-x_{3}=4\\x_{2}+5x_{3}=-1\\4x_{1}+5x_{2}+5x_{3}=8](/tpl/images/2370/2635/82e10.png)
A. If the system of equations is represented by a matrix equation Ax = b, where x =
and b =
, then what is the size f matrix A? Explain you reasoning.
B. What are the entries, in order from left to right, in the second row of A? Explain your reasoning.
C. Suppose that more equations, but not more variables, were included in the system of equations above. How would the size of matrix A and the sizes of vectors x and b change, if at all? Explain and be specific about any changes you describe.
