Answer 2

80+4(7у-3)>5(3у+5)-30у
80+28у-12>15у+25-30у
68+28у-12>-15у+25
28у+15у>25-68
43у>-43
у>-1

Answer 3

To solve the inequality, let's simplify both sides of the equation step by step:

80 + 4(7у - 3) > 5(3у + 5) - 30у

First, simplify the expressions inside the parentheses:

80 + 28у - 12 > 15у + 25 - 30у

Combine like terms:

28у + 68 > -15у + 25

Move all the terms involving у to one side of the inequality and the constant terms to the other side:

28у + 15у > 25 - 68

Combine like terms again:

43у > -43

To isolate у, divide both sides of the inequality by 43 (since 43 is positive, we don't need to change the direction of the inequality):

у > -43/43

Simplifying further:

у > -1

Therefore, the solution to the inequality is у > -1.
