Question

How would you solve this for c?

Answer 1

Answer: c = -fd + ab

This is the same as saying c = ab - fd

==================================================

Work Shown:

`(ab-c)/(d) = f\\\\\\ab-c = fd\\\\\\-c = fd-ab\\\\\\c = -fd+ab\\\\\\`

Explanation for each step:

1. This is the original equation.
2. I multiplied both sides by d to undo the division.
3. I subtracted ab from both sides.
4. I multiplied both sides by -1, or I multiplied every term by -1, to fully isolate c.

Answer 2

c = ab - df

Explanation:

ab - c = df

》ab = c + df

c + df = ab

c = ab - df
