Which ordered pair open paren A comma b close paren is the solution to the following system of equations? negative 2 A plus 3 b is equal to 14 A minus 4 b is equal to 3

From the second equation, a − 4b = 3, solve for a to get a = 3 + 4b. Substitute this into the first equation: −2(3 + 4b) + 3b = 14, which simplifies to −6 − 5b = 14, so b = −4. Then a = 3 + 4(−4) = −13, giving the ordered pair (−13, −4), choice C.
