Answer 2

Answer:

7 is 3 more than 4.

Number 5 is 4 less than 9.

Step-by-step explanation:

• let 7 is 'x' more than 4.

• If a number  'a' is x more than another number 'b', then we can get the number 'a' by adding x with another number 'b'.
• So, we can write :

   4 + x = 7

   ⇒   x = 7 - 4

   ⇒ x   = 3.

so, we can say that 7 is 3 more than 4.

• If a number 'y' is 'a' less than 'b' , then we can write

        y - a = b

      or, y = b + a

• Let 'y' is 4 less than 9.

• Hence, we can write the given statement in the following mathematical form:

        y + 4 = 9

   ⇒  y    =  9 - 4

   ⇒  y    =  5.

so, we can say that number 5 is 4 less than 9.
