Chapter 2: Q8 (page 40)

Justify each statement with a property from algebra or property of congruence.
If $2 z 鈭� 5 = 鈭� 3$ then $2 z = 2$ .

Short Answer

Expert verified

From the property of Algebra, it is proved that $2 z = 2$ .

Step by step solution

Step 1. Apply subtraction property of algebra.

If $a = b$ and $c = d$ , then $a 鈭� c = b 鈭� d$ .

Step 2. Description of step.

Add 5 on both sides of the equation $2 z 鈭� 5 = 鈭� 3$ .

$2 z 鈭� 5 + 5 = 鈭� 3 + 5$

Step 3. Description of step.

Simplify the equation mentioned in step 2 to find the value of 2z.

$\begin{matrix} 2 z + 0 = 2 \\ 2 z = 2 \end{matrix}$

Therefore, the value of $2 z$ is 2.
