Let the bigger number is x
And the smaller number is y
According to the question,
x - y = 8
=> x = 8 + y....................(i)
And,
x + 2 = 3 * y
8 + y + 2 = 3 * y ( by (i))
10 + y = 3 * y
=> 10 = 2 * y
=> y = 5
putting value of y in (i)
=> x = 13
Therefore, the numbers are 13 and 5
And the smaller number is y
According to the question,
x - y = 8
=> x = 8 + y....................(i)
And,
x + 2 = 3 * y
8 + y + 2 = 3 * y ( by (i))
10 + y = 3 * y
=> 10 = 2 * y
=> y = 5
putting value of y in (i)
=> x = 13
Therefore, the numbers are 13 and 5

Ques.→The difference between two numbers is 8.if 2 is added to the bigger number the result will be three times the smaller number. find the number.
Solution →
⚪Let one number be x
⚪Let other number be y
[ x > y ]
→ x - y = 8
→ x + 2 = 3y
▪Subtracting these 2 equations,
=> ( x - x ) (-y +3y ) = 10
=> 2y = 10
★ Substitute the value of y in any of the equation :-
=> x - y = 8
=> x - 5 = 8
_______________________________________
→ 13 - 5 = 8 ✔
→ 13 + 2 = 3 ( 5)
= 15 = 15 ✔
Hence it satisfies both the given conditions .
