The sum of two numbers is 11. their difference is 1. find the numbers.

Equations

x + y = 11

x - y = 1          Add these two equations.

2x = 12           The ys cancel out.  Divide by 2

x = 12/2

x = 6

x + y = 11

6 + y = 11   Subtract 6 from both sides.

y = 11 - 6

y = 5

Answer

x = 6

y = 5

definitely a. the others have almost all data points on one side of the line.
