Answer 2

$\displaystyle \tt 9(0,5+1)-3,1(1-y)>5,9+7,2y\\\displaystyle \tt 9\cdot1,5-3,1+3,1y>5,9+7,2y\\\displaystyle \tt 13,5-3,1+3,1y>5,9+7,2y\\\displaystyle \tt 10,4+3,1y>5,9+7,2y\\\displaystyle \tt 3,1y-7,2y>5,9-10,4\\\displaystyle \tt -4,1y>-4,5\\\displaystyle \tt y$

Answer 3

To solve the inequality 9(0.5+1) - 3.1(1-y) > 5.9 + 7.2y, let's simplify the expression step by step:

First, we simplify the left side of the inequality: 9(0.5+1) - 3.1(1-y) = 9(1.5) - 3.1(1-y) = 13.5 - 3.1(1-y) = 13.5 - 3.1 + 3.1y = 10.4 + 3.1y

Now the inequality becomes: 10.4 + 3.1y > 5.9 + 7.2y

Next, let's isolate the terms with "y" on one side: 10.4 - 5.9 > 7.2y - 3.1y 4.5 > 4.1y

To solve for "y," divide both sides of the inequality by 4.1: 4.5/4.1 > y

Simplifying the left side: 1.097560975609756 > y

Therefore, the solution to the inequality is y < 1.097560975609756.
