# How do you solve y+9.4=-12.2?

$y = - 21.6$
Given $y + 9.4 = - 12.2$, we need to isolate $y$ to find its value.
Subtract 9.4 from both sides: $y \setminus \cancel{+ 9.4} \setminus \cancel{\setminus \textcolor{red}{- 9.4}} = - 12.2 \setminus \textcolor{red}{- 9.4}$
Simplify to $y = - 12.2 - 9.4$
Combine the subtraction and you get $y = - 21.6$
