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.
