Answer» Answer: 6x + 3y = 6xy divide each term with xy , =>6/y + 3/X = 6 ---( 1 ) 2x + 4y = 5xy divide each term with xy , we get => 2/y + 4/x = 5 ---( 2 ) Let 1/x = a , 1/y = b 6/y + 3/x = 6 => 6b + 3a = 6 ---( 3 ) 2/y + 4/x = 5 => 2b + 4a = 5 ----( 4 ) In equation (4) , multiply 3 in each SIDE... we get, 6b+12a=15.......(4) from equation(3) and (4), we get 6b + 3a = 6 6b + 12a = 15 __________ -9A = -9 a = ( -9 )/( -9 ) a = 1
PUT the value of a in equation (4), we get... 2b + 4 = 5 2b = 5 - 4 b = 1/2 Now we get the value of a and b.... Therefore , 1/x = a = 1 =>x = 1 , 1/y = b = 1/2 => y = 2 Hope it will HELP you ✌️ |
