Answer:

Answer 2

Step-by-step explanation:

Let the one number be x and another number be 8 - x.

$\underline{ \large \purple{ \mathscr{\dag\:A \bf{ccourding} \: to \: \mathscr {Q} \bf{uestion} ....}}} </p><p>$

10x + (8 - x) + 28 = 10(8 - x) + x

10x + 8 - x + 18 = 80 - 10x + x

9x + 26 = 80 - 9x

9x + 9x = 80 - 26

18x = 54

x = 3

Therefore,

• One number = x = 2
• Other number = (8 - x) = 8 - 3 = 5

Therefore, required no. is 35.
