If you're wondering why this is, it's due to the fact that in chemical reactions, physical appearance of the products changes compared to the reactants.
Answer:

Explanation:
First thing you need to do is simplify the expression by combining like terms:
2 + 2 - 4 + 8d = 4
4 - 4 + 8d = 4
0 + 8d = 4
8d = 4
Next step is you need to try to isolate the unknown on one side of the equation.
To do this, you transpose or you divide both sides of the equation by 8, to keep the equation true:

We simplify the fraction:

If you want to check, just substitute the value of d.
2 + 2 - 4 + 8(1/2) = 4
0 + 4 = 4
4 = 4
Well at first he refused to pay her more, and she leaves in a huff.
but then she came back with company (aka sunny) to collect her money he refuses again
