Best ResponseYou've already chosen the best response.0Adding equation 1 and equation 2 gives, 3x  14 = 0. So x = 14/3, then plugging x into equation 2, you get y = x  4 = 14/3  4 = 2/3

Best ResponseYou've already chosen the best response.0Generally, for these types of questions, you have two algebraic methods to solve them. One is by elimination, and the other is by substitution. Using elimination, you aim to add or subtract the equations to eliminate one of the variables to make the system single variable.
