2*(AB) + 3*(AC) = 77 or, 6*(AB) + 9*(AC) = 231 (x 3) ...................... (1) And, 3*(AB) + 2*(AC) = 73 or, 6*(AB) + 4*(AC) = 146 (x 2) .......................... (2) From, (1) - (2), we get, 5*(AC) = 231 - 146 = 85 or, (AC) = 85/5 = 17 tk Now, replacing the value of (AC) in eq (1), 6*(AB) + 9*17 = 231 or, 6*(AB) = 231 - 153 or, (AB) = 78/6 =13 tkRelated questions
