x + y =36 eq.1
x = 3y eq.2
Substitute value of x (eq.2) to equation 1:
3y + y = 36
4y = 36
y=9
x = 3y
x = 3(9)
x = 27
from equation 1: x + y =36
27 + 9 = 36

Find two numbers whose sum is 24 and such that one is 2 times as large as the other?
Let unknown numbers be 2x and x: 2x+x = 24 3x = 24 x = 8 Therefore the two numbers are 8 and 16
There are 2 numbers whose sum is 99 one number is twice as large as the other number so what is the smallest number?
33 66+33=99
The sum of two numbers is 24 find the numbers whose squares are to be minimum?
12 and 12, whose squares will be 144 each. If either of the numbers is smaller than 12, then the other will be larger than 12 and its square will be larger than 144.
What two numbers whose product is 48 and whose sum is -19?

Find two numbers whose sum is sixty-five and such that one is four times as large as the other?
The answer is X-13 + Y- 52 = Sum 65
Find two numbers whose sum is 24 and such that one is 2 times as large as the other?
Let unknown numbers be 2x and x: 2x+x = 24 3x = 24 x = 8 Therefore the two numbers are 8 and 16
There are 2 numbers whose sum is 99 one number is twice as large as the other number so what is the smallest number?
33 66+33=99
Find two numbers whose sum is 45 and such that one is 4 times as large as the other.?
Let x=smaller #, 4x=larger # x+4x=45 5x=45 Divide both sides by 5. x=9 4x=36
What are a pair of numbers whose greatest common factor is one of the numbers in the pair?
That happens when one of the numbers is a factor of the other.
What are pairs of numbers whose greatest common factor is the same as one of the numbers?
In that case, one of the numbers is a multiple of the other.
Can there be two numbers whose square is same?
No, because the square of a number is that number times itself, so a no two numbers will have the same square.
Which numbers have a least common multiple of 12?
Numbers for which the sum of the digits is divisible by 9. This is also true for 3. There are other divisibility/multiple tests for other numbers (e.g., numbers that are divisible by 5 end in 5 or 0; numbers whose last two digits are divisible by 4 are divisible by 4)
What is the greatest possible product of 2 numbers whose sum is 60?
900 - 30 times 30
What are two numbers whose GCF is 2?
2 and any other even number.
