Q. Solve.

\newline

7(z+2)=49

\newline

Answer:

z=

Identify equation: Identify the equation to solve. $\newline$ We are given the equation $7(z+2)=49$ , which is a linear equation.
Divide to isolate term: Divide both sides of the equation by $7$ to isolate the term $(z+2)$ . Doing this, we get (z+2) = rac{49}{7}.
Calculate division: Calculate the division on the right side of the equation. $49$ divided by $7$ equals $7$ , so the equation simplifies to $(z+2) = 7$ .
Subtract to solve for $z$ : Subtract $2$ from both sides of the equation to solve for $z$ . Subtracting $2$ from both sides gives us $z = 7 - 2$ .
Calculate subtraction: Calculate the subtraction on the right side of the equation. $7 - 2 = 5$ , so the value of $z$ is $5$ .
