Question

Item 5 Solve for b. − 1 3 b=9 What is the answer?

Answer 1

For
`b=(9)/(-13)` so that
`-13 * b=9` .

Explanation:

Given expression

- 13 b = 9

Here, -13 is multiplied with b on solving it gives 9 as answer.

We have to find b so that when it is multiplied with -13 it gives answer as 9.

`-13 * b=9`

When -13 is taken to other side operation gets inverse (multiplication changes to division) and -13 goes other side in denominator as,

`\Rightarrow b=(9)/(-13)`

Thus, for
`b=(9)/(-13)` so that
`-13 * b=9` .

Answer 2

b = -27

Explanation:

-1/3 b = 9

Multiply each side by -3

-3 * -1/3 b = -3 * 9

b = -27
