Chapter 2: Q65. (page 102)

Find the value of $n$ . Then name the property used in each step. (Lesson 1-3)
$(10 - 8) (7) = 2 (n)$

Short Answer

Expert verified

The value of $n$ is $7$ . The property used is substitution property of equality.

Step by step solution

Step 1. State the property.

The substitution property of equality states that for any quantity $a$ , if $a = b$ , then $a$ may be replaced by $b$ in any equality.

Step 2. Write the given equation.

The given equation is $(10 - 8) (7) = 2 (n)$ .

Step 3. Solve the given equation.

Note that $10 - 8 = 2$ .

Put $10 - 8 = 2$ in $(10 - 8) (7) = 2 (n)$ to get,

$(2) (7) = 2 (n)$

This implies that,

$7 = n$ or equivalently $n = 7$ (Substitution property of equality)

So, the solution of the given equation is $n = 7$ and the property used is the substitution property of equality.
