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.
