If |b| is less than or equal to 12, then b is more than or equal to -12 or less than or equal to 12.
Also, b can only be an even number because 2a is always even.
Now, if I understand it correctly, the ordered pairs are
0,12 (0+12)
1,10 (2+10)
2,8 (4+8)
3,6 (6+6)
4,4 (8+4)
5,2 (10+2)
6,0 (12+0)
7, -2 (14-2)
8, -4 (16-4)
9, -6 (18-6)
10, -8 (20-8)
11, -10 (22-10)
12, -12 (24-12)
Is there a way to solve it algebraically?
