Answer» Step-by-step explanation Let the numbers be a and b a + b = 420 ......... (1) a - b = 86 ...........(2) add equation (1) and (2) a + b = 420 a - b = 86 ...................... 2a = 506 a = 253 put a = 253 in equation (1) , we GET a + b = 420 or 253 + b = 420 or b = 167 hence the required number is (a = 253 and b = 167) |
