Brute force and maximal ignorance mode:
0+14=14 0²+14²=196
1+13=14 1²+13²=170
2+12=14 2²+12²=148
3+11=14 3²+11²=130
4+10=14 4²+10²=116
5+9=14 5²+9²=106
6+8=14 6²+8²=100
7+7=14 7²+7²=98
8+6=14 8²+6²=100
9+5=14 9²+5²=106
10+4=14 10²+4²=116
11+3=14 11²+3²=130
12+2=14 12²+2²=148
13+1=14 13²+1²=170
14+0=14 14²+0²=196
Thus, the minimum is at both numbers being 7.

Solve this equation using addition method The sumof two numbers is 21 The difference of the two is 19 what are the two number?
take the 2 numbers to be x and yx + y = 21x - y = 19add the two equations together; the y's will cancel as one is positive, the other negative.x + y + x - y = 402x = 40x = 20substitute in x is 20 to find y20 - y = 19y = 1so the 2 numbers are 20 and 1
