Step-by-step explanation:
Let n = the smaller number, and since the other number is twice the smaller one, then ...
Let 2n = the larger number.
Since "the sum of the two numbers is 51," then we can translate this statement mathematically into the following equation to be solved for n as follows:
n + 2n = 51
Collecting like-terms on the left-hand side of the equation, we get:
3n = 51
Now, divide both sides by 3 in order to isolate and thus solve for the unknown quantity n as follows:
(3n)/3 = 51/3
(3/3)n = 51/3
(1)n = 17
n = 17
Therefore, ...
2n = 2(17)
= 34
CHECK:
n + 2n = 51
17 + 34 = 51
51 = 51
Therefore, the two desired numbers are indeed 17 and 34.
Answer:
Divide both sides by 3 and we see that x=51/3 =17 ... The sum of two numbers is 22, the larger number is two less than twice the ... Let the two numbers be x and y and y is twice of x.
