Question

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

$1.5+n=1.5$

Short answer

The required value is $n=0$. The name of the property is additive inverse property.

Step-by-step solution

Step 1. Isolate the variable.

$\begin{array}{l}1.5+n=1.5\\ n=1.5-1.5\end{array}$

Step 2. Solve for n.

$\begin{array}{l}n=1.5-1.5\\ n=0\end{array}$

Hence, the value of $n=0$.

Step 3. Additive inverse 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.

Thus, the required property is additive inverse property.
