Chapter 2: Q73. (page 96)

Find the value of n in each equation. Then name the property that is used.

4鈭�n=0

Short Answer

Expert verified

The required value is n=4. The name of the property is Additive inverse property.

Step by step solution

01

Step 1. Isolate the variable.

4鈭�n=0鈭�n=鈭�4

02

Step 2. Remove the negative sign.

鈭�n(鈭�1)=鈭�4(鈭�1)n=4

Hence, the value of n=4.

03

Step 3. Identify the property.

The additive inverse property says that the additive inverse of a number is its opposite number.

If a number is added to its inverse, then the sum of both the number becomes zero.

Since, the sum of 4 and -4is equal to zero.

Thus, the required property is additive inverse property.
