Chapter 3: Q2. (page 126)

Solve the equation. Check your solution. $2 (s - 1) = 6$

Short Answer

Expert verified

The solution for the equation $2 (s - 1) = 6$ is $s = 4$ .

Step by step solution

– Separate the variable and constants

Write the original equation and separate the variable and constants.

$\begin{matrix} 2 (s - 1) = 6 \\ 2 s - 2 = 6 \\ 2 s - 2 + 2 = 6 + 2 \\ 2 s = 8 \end{matrix}$

– Solve for s

Now, divide both sides of the equation by 2.

$\begin{matrix} \frac{2 s}{2} = \frac{8}{2} \\ s = 4 \end{matrix}$

Therefore, the solution of the equation is $s = 4$ .

– Check the solution

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

$2 (s - 1) = 6$

Now, substitute $s = 4$ and check the result.

$\begin{matrix} 2 (4 - 1) = 6 \\ 2 (3) = 6 \\ 6 = 6 \end{matrix}$

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