Answer» Heya !! Here's your answer.. ⬇⬇ ________________________________ Let the ten's place = x unit place = y original no. = 10X + y ➡Given that a two digit NUMBER is 4 more than 6 times SUM of digits. 10x + y = 4 + ( x + y )6 10x + y = 4 + 6x + 6y 10x - 6x + y - 6y = 4 4x - 5y = 4 ----(1) ➡ if 18 is subtracted from the number the digit GET reversed. Reversed no. = 10y + x 10x + y - 18 = 10y + x 10x - x + y - 10y = 18 9x - 9y = 18 9 ( x - y ) = 18 x - y = 2 ----(2) Multiply eq.(2) by 4 and subtract it from eq. ( 1 ) 4x - 5y = 4 -4x + 4y = -8 ------–--–-–------- - y = -4 y = 4 Put value of ( y ) in eq. (2) x - y = 2 x - 4 = 2 x = 2 + 4 x = 6 Original no. = 10x + y = 10( 6 ) + 4 = 60 + 4 = 64 ________________________________ Hope it helps. Thanks :)
