Which ordered pair open paren A comma b close paren is the solution to the given system of linear equations? 3 A plus b is equal to 10 negative 4 A minus 2 b is equal to 2

The equations are 3a + b = 10 and −4a − 2b = 2. Divide the second equation by −2 to get 2a + b = −1; subtracting this from the first gives a = 11, and then b = 10 − 3(11) = −23. The solution is (11, −23), choice B.
