Answer 1

well just do 15-7 subtract 7 and you get 8

Answer 2

Answer:

The required two subtraction equation is (10 - 5) + (5 - 2)

Step-by-step explanation:

Consider the provided information,

We need to write two subtraction equations to show how to find 15-7

First consider the number 15

The number 15 can be written as:

15 = 10 + 5

The number 7 can be written as:

7 = 5 + 2  

Now substitute the respective values in original expression.

(10 + 5) - (5 + 2)

Open the parentheses

10 + 5 - 5 - 2

Now rearrange them as shown below:

10 - 5 + 5 - 2

Close in parentheses.

(10 - 5) + (5 - 2)

Thus, the required two subtraction equation is (10 - 5) + (5 - 2)
