Solve. 7(2z-4)=0 Answer: z=

Simplify the equation: First, we need to simplify the equation by distributing the 7 across the terms inside the parentheses. 7 * 2z - 7 * 4 = 0 14z - 28 = 0Addition to isolate variable: Next, we add 28 to both sides of the equation to isolate the term with the variable z. 14z - 28 + 28 = 0 + 28 14z = 28Divide to solve for z: Now, we divide both sides of the equation by 14 to solve for z. 14z / 14 = 28 / 14 z = 2

Q. Solve.

\newline

7(2 z-4)=0

\newline

Answer:

z=

Simplify the equation: First, we need to simplify the equation by distributing the $7$ across the terms inside the parentheses. $7 \times 2z - 7 \times 4 = 0$ $14z - 28 = 0$
Addition to isolate variable: Next, we add $28$ to both sides of the equation to isolate the term with the variable $z$ . $\newline$ $14z - 28 + 28 = 0 + 28$ $\newline$ $14z = 28$
Divide to solve for z: Now, we divide both sides of the equation by $14$ to solve for z. $\newline$ $\frac{14z}{14} = \frac{28}{14}$ $\newline$ $z = 2$
