Question

14-10c=94

Answer 1

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

Answer 2

how did you put -14 next to 14-10c

Answer 3

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

Answer 4

from which

Answer 5

94 and which one

Answer 6

And \(14-10c\).

Answer 7

??????

Answer 8

may you please show me step by step im very confused

Answer 9

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:
\[
\begin{align*}
5 &= 5\\
5 + 2 &= 5+2\\
7 &= 7
\end{align*}
\]

Answer 10

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

Answer 11

The thing with my math teacher she wants us to show it step by step

Answer 12

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

Answer 13

so

Answer 14

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

Answer 15

?

Answer 16

Well, what's \(94-14\).

Answer 17

so its

Answer 18

14-10c=94
-14 =-14

Answer 19

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