Q. Solve for

z

.

\newline

2z - 2 = 6

\newline

z =

_____

Isolate variable term: Isolate the variable term on one side of the equation. $\newline$ $2z - 2 = 6$ $\newline$ $2z - 2 + 2 = 6 + 2$ (adding $2$ to both sides) $\newline$ $2z = 8$
Divide by coefficient: Divide both sides of the equation by the coefficient of $z$ to solve for $z$ . $\newline$ $2z = 8$ $\newline$ $\frac{2z}{2} = \frac{8}{2} \text{ (dividing both sides by 2)}$ $\newline$ $z = 4$
