What is the solution to this system of linear equations? 2 x plus y is equal to 1; 3 x minus y is equal to negative 6

Add the equations 2x + y = 1 and 3x − y = −6 to eliminate y: 5x = −5, so x = −1. Substitute into the first equation: 2(−1) + y = 1, which gives y = 3. The solution is (−1, 3), choice B.
