Answer 1

Answer:

33

Step-by-step explanation:

let the digit at tens place be x

so, x+2x-3=12

3x-3=12

3x=12-3

3x=9

x=9/3

x=3

tens place : 3

units place: 2x-3= 3

So, the number is 33

Answer 2

Answer:

5 + 7

Step-by-step explanation:

Let the number at tens place be x

Then, according to the question

x + ( 2x - 3 ) = 12

3x - 3 = 12

3x = 12 + 3

3x = 15

x = 15/3

x = 5

5 + ( 2*5 -3 )

5 + 7.....Answer
