What value of z makes the equation below true? 2z-4=12 2 7 8 9

Set up equation: Set up the equation that needs to be solved. The equation given is 2z - 4 = 12. We need to solve for z.Add 4 to isolate: Add 4 to both sides of the equation to isolate the term with the variable z. 2z - 4 + 4 = 12 + 4 This simplifies to: 2z = 16Divide by 2: Divide both sides of the equation by 2 to solve for z. 2z / 2 = 16 / 2 This simplifies to: z = 8

Set up equation: Set up the equation that needs to be solved. $\newline$ The equation given is $2z - 4 = 12$ . $\newline$ We need to solve for $z$ .
Add $4$ to isolate: Add $4$ to both sides of the equation to isolate the term with the variable $z$ . $2z - 4 + 4 = 12 + 4$ This simplifies to: $2z = 16$
Divide by $2$ : Divide both sides of the equation by $2$ to solve for $z$ . $\frac{2z}{2} = \frac{16}{2}$ This simplifies to: $z = 8$
