What are the possible values that can be substituted for y to make the inequality 7y - 9 < 30 true?
To solve the inequality 7y - 9 < 30, we need to find the possible values for y that make this inequality true. Here's how we can do that:
Step 1: Add 9 to both sides of the inequality to isolate the term with y:
7y - 9 + 9 < 30 + 9
7y < 39
Step 2: Divide both sides of the inequality by 7 to solve for y:
(7y) / 7 < 39 / 7
y < 5.57
Therefore, the possible values that can be substituted for y to make the inequality 7y - 9 < 30 true would be any value less than 5.57.
