у-4 < y-7

0 < - 3  это неверно

Поэтому ответ ∅

Answer 2

Answer 3

To solve the inequality 9y-4(1+2y)<y-7, we need to simplify and isolate the variable y.

Let's simplify the left side of the inequality:

9y - 4(1+2y) < y - 7

Distribute -4:

9y - 4 - 8y < y - 7

Combine like terms:

y - 4 < y - 7

Now, let's isolate the variable y:

Add 4 to both sides of the inequality:

y - 4 + 4 < y - 7 + 4

Simplify:

y < y - 3

Since the variable y appears on both sides of the inequality, there is no single solution for y that will satisfy the inequality. Therefore, the inequality has no solution.
