Answer:
-13.8y
Step-by-step explanation:
Since these all have the same variable you don't need to worry that much. Let's take away the y to make it easier. Now you just subtract normally.
1.8 - 9.3
A trick that I use is that I subtract 9.3 - 1.8, and then add a negative sign. So that is -7.5
Then, subtract -7.5-6.3. You add these because they have the same symbol. So it is -13.8
We can't forget about the variable!! So it is -13.8y
Hope this helps!!
