Answer:
To solve the inequality -5.3 + y < -9.1 for y, we need to isolate y on one side of the inequality sign.
First, let's isolate y by adding 5.3 to both sides of the inequality:
-5.3 + 5.3 + y < -9.1 + 5.3
Simplifying this, we have:
y < -3.8
So the solution to the inequality -5.3 + y < -9.1 is y < -3.8.
