Chapter 1.1, Problem 8E

To determine

To solve the equation

  $s-2=1$

Answer to Problem 8E

  $s=3$ is the solution.

Explanation of Solution

Given: Equation: $s-2=1$

Formula Used:

The addition property of equality states that if we add or subtract the same number to both sides of an equation, the sides remain equal.

Calculation:

Given: Equation: $s-2=1$

To solve the equation, Adding $2$ to both the sides as “Addition property of equality states that if we add or subtract the same number to both sides of an equation, the sides remain equal.”

  $\begin{array}{l}s-2=1\\ s-2+2=1+2\\ s=3\end{array}$

Thus, the solution is $s=3$ .

Now, putting the value of $s=3$ in the L.H.S. of the equation, we have:

  $3-2=1$

And R.H.S. of the equation is $1$ .

Hence, L.H.S. $=$ R.H.S.

Thus, the solution is correct.

Conclusion:

Hence, the solution is $s=3$ .
