Answer:
Explanation:
To solve the inequality, we need to isolate y on one side of the inequality sign. We can do this by adding 21 to both sides of the inequality:
y - 21 + 21 < 85 + 21
Simplifying, we get:
y < 106
So, the solution to the inequality is y < 106.
When graphing the solution on a number line, we would put an open circle at 106 and draw the line towards the left, indicating that y can take on any value less than 106.
