Answer:
The numbers are 35 and 7.
Step-by-step explanation:
Given that:
A positive number is 5 times another number.
21 is added to both the numbers then one of the new numbers becomes twice the other new number.
To Find:
What are the numbers?
Let us assume:
A positive number = 5x.
Another number = x
After adding 21 to both the numbers:
Positive number = (5x + 21)
Another number = (x + 21)
Finding the numbers:
According to the question.
⟶ (5x + 21) = 2(x + 21)
⟶ 5x + 21 = 2x + 42
⟶ 5x - 2x = 42 - 21
⟶ 3x = 21
⟶ x = 21/3
⟶ x = 7
Numbers are:
Positive number = 5x = 5 × 7 = 35
Another number = x = 7
Answer:
Here is your answer
Step-by-step explanation:
let the smaller number = x
bigger number = 5x. -----(we need this.)
if 21 is added to both; 5x+21 = 2×(x+21)
5x + 21 = 2x + 42
5x - 2x = 42 - 21
3x =. 21
x = 21/3= 7
So the positive number is = 5×7 = 35
answer is 35
