Question

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

Answer 1

`y=-21.6`

Explanation:

Given `y+9.4=-12.2`, we need to isolate `y` to find its value.

Subtract 9.4 from both sides: `y\cancel(+9.4)\cancel(\color(red)(-9.4))=-12.2\color(red)(-9.4)`
Simplify to `y=-12.2-9.4`
Combine the subtraction and you get `y=-21.6`
