Solve each equation. Check your solution.
$14 = \frac{6 + z}{- 2}$

Short Answer

Expert verified

The solution of the given equation is $z = - 34$ .

Step by step solution

Step 1. Write the given equation.

The given equation is “ $14 = \frac{6 + z}{- 2}$ ”.

Step 2. Solve the given equation.

Solving,

$14 = \frac{6 + z}{- 2}$ (Given equation)

$14 \times (- 2) = \frac{6 + z}{- 2} \times (- 2)$ (Multiply both sides by $- 2$ )

$- 28 = 6 + z$ (Simplify)

$- 28 - 6 = 6 + z - 6$ (Subtract 6 from both sides)

$- 34 = z$ (Simplify)

$z = - 34$ (Write the variable on the left-hand side)

So, $z = - 34$ is the solution of the given equation.

Step 3. Check the obtained solution.

Put $z = - 34$ in the given equation $14 = \frac{6 + z}{- 2}$ to get,

$\begin{array}{l} 14 = \frac{6 - 34}{- 2} \\ 14 = \frac{- 28}{- 2} \\ 14 = 14 \end{array}$

Since the value obtained on the left-hand side and right-hand side are equal, the obtained value is indeed a solution of the given equation.
