700 -1 -200
75 1 5000
Step-by-step explanation:
1. the rule for the required matrix is:
[tex]\left[\begin{array}{ccc}x_1;y_1;a\\x_2;y_2;b\end{array}\right][/tex]
2. if to re-write the given equations, then:
700x-y= -200 and 75x+y=5000.
3. Finally, the answer is:
column№1 | column№2 | column№3
==============+===========+=============
row№1 700 | -1 | -200
row№2 75 | 1 | 5000
