Answer 1

вот, надеюсь правильно

Answer 2

To solve the inequality, we'll follow the standard rules of algebra to isolate the variable "y." Remember to perform the same operation on both sides of the inequality to maintain its balance. Let's proceed step by step:

1. Distribute the numbers outside the parentheses: 80 + 4 * 7y - 4 * 3 > 5 * 3y + 5 * (-30y)

2. Simplify the expressions: 80 + 28y - 12 > 15y - 150y

3. Combine like terms on both sides: 68 + 28y > -135y

4. Bring the "y" terms to one side of the inequality: 68 + 28y + 135y > 0

5. Combine the "y" terms: 163y + 68 > 0

6. Isolate "y" on one side: 163y > -68

7. Divide by the coefficient of "y," which is 163 (and since 163 is positive, the inequality sign remains unchanged): y > -68/163

So, the solution to the inequality is: y > -68/163.
