Answer:
Step-by-step explanation:
- other number = x
- A positive number is 5 times another number = 5x
- If 21 is added to both the numbers,
→ x + 21
→5x + 21
- then one of the new numbers becomes twice the other new number
→5x + 21=2( x + 21 )
5x + 21=2x+42
5x-2x=42-21
3x=21
x=21/3
x=7
- other number → x=7
- A positive number is 5 times another number →5x=5×7=35
- new number→2x= 2×7=14
