Question

the sum of the digit of a 2 digit number is 7 if the digits are reversed, the new number increased by 3 equal 4 times the original number find the original number​

Answer 1

Answer:

Step-by-step explanation:

We know that the sum of the digits is 7, that’s why we can let the numbers be x and (x-7)

If you agree with the previous statement, then we can let the original number be

10(x) + (x-7)

We multiply x by 10 because it is in the TENS place

So when the number is reversed it will become

10(x-7) + x

We Know That

(10(x) + (x-7) ) * 4 =( 10(x-7) + x) + 3

Solving this equation we get........
