Answer 3

can you explain how please?

Answer 4

first find a common denominator by multiplying the term 7/3d by (5/5), and then multiplying the term 6/5d by (3/3), so that in the end you will obtain:
(35 + 18)/15d or 53/15d
so 53/15d = -5
to get the variable d out of the denominator, multiply each side by a factor of 15d to get:
53 = -75d, divide d by -75 to get d = -53/75
