Potw answer
1. Answer: (5, 0); (4, 1); (1, 2); and (2, 3)
Youcouldsubtract3frombothsides.
ab+ a-3b-3 = 5 -3
Then you could factor the expression as follows:
(a-3)(b+ 1) = 2
You could use a table to find appropriate values for aand b.
(5,0);(4,1);(1,-2);and (2,-3) are the desired solutions.
a-3 b+ 1 ab
2 1 5 0
-2 -1 1 -2
1 2 4 1
-1 -2 2 3
