Question

seven times a two digit number equal four times the number with digits reversed find the number if the sum of the digits is 3​

Answer 1

Step-by-step explanation:

Let the two digit number is 10x+y

The number with the digit reversed 10y+x

Given:- 1)7(10x+y)=4(10y+x). 2)x+y=3

1)70x+7y=40y+4x

66x=33y

2x=y

x+y=3

x+2x=3

3x=3

x=1

y=2x=2
