Justify each statement with a property from algebra or property of congruence.

If $2z-5=-3$ then $2z=2$.

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

If $a=b$ and $c=d$, then $a-c=b-d$.

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

$2z-5+5=-3+5$

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

$\begin{array}{c}2z+0=2\\ 2z=2\end{array}$

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