let larger number be xand smaller number be y First condition Dividend = divsor * quotient + remainder3x= y*4+3 3x=4y+33x-4y=3 second condition7y=5x+1 7y-5x=1 3 x -4 y = 3 .............1
-5 x + 7 y = 1 .............2 Eliminate y multiply (1)by 7 Multiply (2) by 4 21 x -28 y = 21 -20 x + 28 y = 4 Add the two equations 1 x = 25 / 1 x = 25 plug value of x in (1) 3 x -4 y = 3 75 -4 y = 3 -4 y = 3 -75-4 y = -72 y = 18 1x= 25 y= 18
hope it may help u.
thanks..
