Question

The sum of two numbers is s. Suppose 3 is added to each number and then each of the resulting numbers is doubled. What is the sum of the final two numbers?

Answer 1

Answer:

6

Step-by-step explanation:

Let the numbers be x, s-x

According to the statement;

2x= x+3

∴x=3

2(s-x) =s-x+3

2s-2x= s-x+3

2s-s-2x+x=3

⇒s - x=3

∴ sum of the final two numbers:

x+s-x= 3+3=6
