Question

Step by step explanation pls?? :d

Answer 1

-7/15 look at the other answer

Answer 2

-7/15

Explanation:

You want to isolate the d variable so you take out anything on the side of d to make d alone. To make d isolate the 15/42 has to go.

So...multiply

`(15)/(42)`*
`(42)/(15)` right side

the answer to the equation above is 1. d is now alone, because 1*d is just d.

Since you multiplied 42/15 on the right, you've to do the same thing on the left.

`(42)/(15)`*
`(-(1)/(6))` left side

Divide the 6 by itself and also by 42. Or multiply the numerator and denominator.

The answer you get is -7/15.
