Answer:

Step-by-step explanation:

ok now,

X + y = 11  ----------> equation 1

10y +x = 10x +y -45    ----------> equation 2 

9y-9x =-45

y-x = -5

simplifying equation 2, then proceed solving

x+y =11             add the two equations

-x +y = -5 (+)

---------------------

2y= 6

y=3

substitute to the 1st equation

x + y = 11 

x + 3 = 11 

x = 8 

83 is original,

38 is reverse

if you are not sure then there is a checking method so

for checking, subtract the numbers . . . 

83-38 =45 ----------------------(simple )

pls mrk as brainliest :) i took effort to answer this question plss mrk can u :)

Answer:

83

Step-by-step explanation:

Hii mate,

Let the unit's place digit be x

and ten's place digit be y

According to question,

x+y=11

=>y=11-x    ......(1)

Original number (yx)=10y+x

when the number is reversed (xy)=10x+y

According to question,

Reversed number = Original number - 45

=>10x+y=10y+x-45

=>9x-9y+45=0

=>9(x-y+5)=0

=>x-y+5=0         .......(2)

Putting value of y from (1) in (2), we get

x-(11-x)+5=0

=>x-11+x+5=0

=>2x-6=0

=>2x=6

=>x=3

so, y=11-x=11-3=8

Hence,

Original number=10y+x=10(8)+3=80+3=83

So, reverse number=38

difference=83-38=45

so, it's also verified that our answer is correct.

HOPE IT HELPS,

PLEASE THANK, FOLLOW AND MARK AS BRAINLIEST.
