Question

The sum of the digits of a two-digit number is 10. If the digits are reversed, then the new number is 36 more than the original number. Identify the two-digit number​

Answer 1

Answer:

37 is original number

Step-by-step explanation:

lets say the number is made up of x and y digits and y is UNIT DIGIT :

so number is originally,

x*10 + y

also given in question that

x+y=10 ... equation 1

when you swap digits number becomes 36 more than original number  so we can write...

y*10 + x =36 + x*10 + y ..... simplify it and you get

y - x =4 .... equation 2

to solve this, simple add equation 1 and equation 2 like:

x + y + y - x = 10 +4 =14

so y =7 and x=3

original number becomes = 3*10 + 7 =37
