If the equation is
7-8y%3E5-7y
then this solution is correct
- First start off by isolating the variable
7-8y%3E5-7y
- add 7y to both sides
%287-8y%29%2B7y%3E%285-7y%29%2B7y
7-8y%2B7y%3E5-7y%2B7y
7-1y%3E5
- next subtract 7 from each side
%287-1y%29-7%3E%285%29-7
7-7-1y%3E5-7
-1y%3E-2
- the next step is a little tricky to remember becuase whenever the sign of coefficient of the variable is changed then the inequality sign must be flipped
%28-1y%29%2A%28-1%2F1%29%3E%28-2%29%2A%28-1%2F1%29
y%3C2
- and your answer is y<2
