Please mark Brainliest if it is right

Let the no.s are 4x , 5x and 6x

so given is that,

4x + 6x = 5x + 55

10x -5x = 55

5x = 55

x = 55/5 = 11

S the no.s are :

4x = 44

5x = 55

6x = 66

Answer 2

Let the numbers be 4x,5x,6x
sum of largest and smallest numbers=
third no. + 55
=>6x+4x = 5x+55
=>10x=5x+55
=>10x-5x=55
=>5x=55
=>x=55/5
=>x=11

So the numbers are 4x = 44
5x = 55
6x = 66
