    \[ \begin{align*} (14-10c) - 14 &= 94 - 14\\ -10c &= 80\\ \frac{-10c}{-10} &= \frac{80}{-10}\\ c &= -8 \end{align*} \]

    I was just showing that I was subtracting 14 from both sides.

    So when you have an equation (with an equal sign saying one thing is equivalent to another), in order to preserve the equality, you have to do the same thing ot both sides of the equation. For example, if you have \(5=5\), if you add \(2\) to both sides, the equality is still preserved: \[ \begin{align*} 5 &= 5\\ 5 + 2 &= 5+2\\ 7 &= 7 \end{align*} \]

    So I did the same thing with your equation, except instead of adding two, I subtracted 14.

    Yeah, so the first step would be subtracting 14 from both sides.

    14-10c=94 -14 =-14 --------------- -10c=94

    14-10c=94 -14 =-14

    Well, what I was saying is that the final equation you wrote shouldn't have been \(-10c = 94\), it should be \(-10c = 80\), as \(94-14 = 80\).
