Chapter 2: Q. 10E (page 105)

Solve the equation. Check your solution.
$- 5.2 a = 1.3$

Short Answer

Expert verified

Solution of given equation is $a = - 0.25$ .

Step by step solution

Step 1. Solve for value of a

$- 5.2 a = 1.3$

Dividing with $- 5.2$ on both sides, we get

$\begin{matrix} \frac{- 5.2 a}{- 5.2} = \frac{1.3}{- 5.2} \\ a = \frac{1.3}{- 5.2} \\ a = (- 1) \frac{1.3}{5.2} \\ a = - 0.25 \end{matrix}$

Step 2. Verification of our solution

For checking our answer, substitute $a = - 0.25$ in given equation $- 5.2 a = 1.3$ .

On substituting, we get

$\begin{matrix} - 5.2 a = 1.3 \\ (- 5.2) (- 0.25) = 1.3 \\ 1.3 = 1.3 \end{matrix}$

Step 3. Conclusion

Here, both sides of above expression are equal.

So, our answer is true.
