#### Answer

a is not a solution.
b is a solution.

#### Work Step by Step

Check each ordered pair by replacing x and y in the system of equations.
a. 2(2) + 3(2) = 1
4 + 6 = 1
10 = 1; False
b. 2(-1) + 3(1) = 1
-2 + 3 = 1
1 = 1; True
3(1) - (-1) = 4
3 + 1 = 4
4 = 4; True
Only b satisfies both equations, so b is a solution.
