2x=18
x=18/2
x=9

1st no= 5*9=45
2nd no= 3*9=27

Answer 2

Hello !
__________________________________________________________
Let one number be x 
Let second number be y 

it is given that x /y = 5/3 

then y = 3/5 x 

ATGC 

x -y = 18 

x -(3x/5) = 18 

5x - 3x /5  = 18

2x /5 = 18 

2x     = 90 

x       = 45 

as y  = 3(45)/5 = 27 

so , two numbers are 45 and 27
