Chapter 3: Q8C. (page 120)

Solve the equation. Check your solution.
$2= \frac{d}{5} -1$

Short Answer

Expert verified

The solution for the equation $2 = \frac{d}{5} - 1$ is . $d = 15$

Step by step solution

– Separate the variables and constants

Write the original equation and separate the variables.

$\begin{matrix} 2 = \frac{d}{5} - 1 \\ 2 + 1 = \frac{d}{5} \\ 3 = \frac{d}{5} \end{matrix}$

– Solve for n

Multiply both sides of the equation $3 = \frac{d}{5}$ by 5 and simplify.

$\begin{matrix} 3 \times 5 = \frac{d}{5} \times 5 \\ d = 15 \end{matrix}$

Therefore, the solution of the equation is $d = 15$ .

– Check the solution

To check the solution, write the original equation and substitute the value of d.

$2 = \frac{d}{5} - 1$

Now, substitute $d = 15$ and check the result.

$\begin{matrix} 2 = \frac{15}{5} - 1 \\ 2 = 3 - 1 \\ 2 = 2 \end{matrix}$

As the left-hand side is equal to right hand side, this signifies that the solution is correct.
