$d=-1.5$

We solve this by doing distribution.

$5(-6-3d)=3(8+7d)$

This means that we "distribute" the $5$ to everything in the parenthesis and "distribute" the $3$ to everything to its parenthesis:

$-30-15d=24+21d$

Now we need to put all the variables on one side and the numbers on the other side of the equation:
$-36d=54$

$d=-1.5$

Hope this helps!

$d=-3/2$

$5(-6-3d)=3(8+7d)$
$rArr -30-15d=24+21d$
$rArr 36d=-54$
$rArr d=-54/36$
$:. d=-3/2$

That's it,
Hope it helps :)
