Submit Answer

Distribute $7$ to terms: Distribute the $7$ to both terms inside the parentheses. $\newline$ We need to apply the distributive property, which states that $a(b + c) = ab + ac$ . In this case, we have $7(z - 2)$ , which becomes $7\cdot z - 7\cdot 2$ . $\newline$ Calculation: $7z - 14 = 28$
Add $14$ to both sides: Add $14$ to both sides of the equation to isolate the term with the variable $z$ . We want to get $z$ by itself on one side of the equation, so we need to undo the subtraction of $14$ by adding $14$ to both sides. Calculation: $7z - 14 + 14 = 28 + 14$ , which simplifies to $7z = 42$
Divide by $7$ : Divide both sides of the equation by $7$ to solve for $z$ . Now that we have $7z = 42$ , we can find $z$ by dividing both sides by $7$ . Calculation: $\frac{7z}{7} = \frac{42}{7}$ , which simplifies to $z = 6$
