Step-by-step explanation:
Sum of two no is = 15
let 1st no be x
2nd no = (15 - x)
the new 1st no = 2x
the new 2nd no => 3(15 - x) = 45 - 3x
sum of new numbers = 35
Equation :
=>2x + ( 45 - 3x) = 35
=> 2x + 45 - 3x = 35
=> 2x - 3x = 35 - 45
=> - x = - 10
=> x = 10 (by cutting out '-' from 2 no as they are same)
Original 1st no = 10
Original 2nd no = 5
Verification : twice of 10 = 20
thrice of 2nd no = 15
Addition => 20 + 15 = 35
Hence verified
