If Kelly's first step is to subtract 8 from both sides of the equation, then the equation she is solving likely has a "+8" term on one side. A common structure of such an equation could be:
\[ x + 8 = c \]
where \( c \) is some constant. Subtracting 8 from both sides would yield:
\[ x + 8 - 8 = c - 8 \] \[ x = c - 8 \]
Another possibility could be if she wants to isolate a variable, for example:
\[ y + 8 = x \]
In this case, subtracting 8 from both sides would look like:
\[ y + 8 - 8 = x - 8 \] \[ y = x - 8 \]
These are just a few examples, but the key is that the original equation contains +8 on one side. If you have a specific equation in mind, feel free to provide it for a more precise answer!
