the sum of two numbers is 12 and their quotient is 7 what are the 2 numbers
Answers
Let the two numbers be :- x, y
Solution :-
x + y = 12
=> x = 12 - y
x / y = 7
=> x = 7y
12 - y = 7y
=> 12 = 8y
=> y = 12 / 8
=> y = 3/2
Answer:
- The two numbers whose sum is 12 and quotient is 7 are 10.5 and 1.5
Given :
- The sum of two numbers is 12.
- Their quotient is 7.
To find :
- The two numbers =?
Step-by-step explanation:
Let one number of the two numbers be x.
Then, the other number automatically becomes (12 - x) Since, it has been given in the question that the sum of both the number is 12.
So, the first equation between the two number is,
x + (12 - x) = 12
Now,
Let, x > (12 - x)
So, we can form another equation between the two numbers and i.e.,
➮ x/12-x = 7
➮ x = 7 (12-x)
➮ x = 84 - 7x
Now,
We shall the put the above obtained value of x = (84 - 7x) into the first equation.
So we have,
➮ x + (12 - x) = 12
➮ (84 - 7x) + (12 - x) = 12
➮ 84 - 7x + 12 - x = 12
➮ -8x = 12 - 12 - 84
➮ -8x = 12 - 96
➮. -8x = - 84
➮ x = - 84/-8
➮ x = 10.5
And, another number is (12 - x) which would be,
12 - 10.5 = 1.5
Hence,
The two numbers whose sum is 12 and quotient is 7 are 10.5 and 1.5
