Rather than substituting and finding,it is always better to answer it basically. let x be the smaller number,then other number as per given condition is 5x + 13.again it is given that their difference is 61
ie 5x + 13 - x = 61
4x = 48
x = 12
so 12 is the smaller number.then the larger number will be 5(12) + 13 = 73. so ans 12,73
