Let's take a look at our problem:
-7 = 7d - 8
To solve for this, we need to isolate the variable and then simplify if needed.
To clarify, the variable is (usually) a letter that represents a constant value. Our variable is "d".
-7 = 7d - 8
Isolate 7d by adding 8 to both sides.
-7 + 8 = 1
We're now left with:
1 = 7d
To solve for d, divide both sides by 7.
1 / 7 = 1/7
7d / 7 = d
We are now left with the solution:
d = 1/7
I hope this helps!
