heya mate there's your answer

let one no. be x

according to the given conditions another number exceeds by 9

so another number be x+9

x+x+9=81

2x+9=81

2x=81-9

2x=72

x=36

So one no.is 36 another is x+9=36+9=45

So numbers are 36 and 45.

Answer 2

let the 1 no. ne X and other be Y

so. according. to the condition :

X-Y=9

given;X+Y=81

now add both the equation and by adding the Y terms cut out so resultant will be ;

2X=81+9

2X=90

X =45

put the value in equation

45-Y=9

Y=45-9

Y=36
