Question

5/6 d = -15? I don't understand

Answer 1

.


`(5)/(6) d = - 15`
First you have to simplify 5/6d to 5d/6 as shown below

`(5)/(6) d = (5d)/(6)`
Then multiple both sides by 6 because you are trying to solve for d

`5d = - 15 * 6`
Multiply -15 and 6 to get -90

`5d = - 90`
Divide -90 by 5

`d = ( - 90)/(5)`

`d = - 18`
Then if you check it, it will give you -15 as your answer

`(5)/(6) * - 18 = - 15`

`(5 * - 18)/(6) = - 15`

`( - 90)/(6) = - 15`

`- 15 = - 15`
