Answer 2

Find the two digit number

Definition:

Two digit numbers are the numbers that have two digits and they start from the number 10 and end on the number 99.They cannot start from zero because in that case it will be considered as a single digit number.

Step-by-step explanation:

Let x be the number in the ones digit or units place and according to the given the number in the tenths place is one more than ones place ,so the number in the tenths place is $x+1$.

As per the given,if we add both the digit ,it gives the sum of 7,that is

[tex]x+x+1=7\\ 2x+1=7\\ 2x=7-1\\ 2x=6\\ x=3[/tex]

The digit in one place is 3 ,and the digit in tenths place is $x+1=3+1=4$

Therefore,the two digit number is 34.
