Let the digit in units place be y

the digit in tens place be x


Then, number is 10x + y



Digit in the tens place of half of the number =y


Digit in the units place of half of the number = (x+1)


Therefore, half of the number = 10y+(x+1)


(10x+y)/2 = 10y+x+1

10x+y = 20y+2x+2

8x−19y = 2 <==equation 1

x+y=7

(x+y=7)8

8x + 8y = 56 <==equation 2



  8x + 8y  = 56

- (8x−19y = 2)

______________

        27y = 54

            y = 2



x=7− y

x=7 - 2

x = 5



The number is 52.




this is what I figured out on some paper I hope this helps you and you understand what I'm saying. GOOD LUCK. you probably don't need it though. REMEMBER YOU GOT THIS.
