    I honestly can't read the first two :( Do you think you can try to draw it using the draw tool?

    \[\frac{y}{2} <-3\] I will give you en example for this one: If you have \[\frac{a}{5}<-2\] => \[5 \cdot \frac{a}{5} <-2 \cdot 5\] \[a<-10\] See you can see what is going on in this example.... Hint multiple 2 on both sides for that problem..

    No to undo multiplication by -1.5 you divide by -1.5 But when you multiply or divide by a negative on both sides this flips the inequality sign
