Answer:
Take 3y to the other side = y-7<0 and take - 7 to the other side y<7
Second one has to inequalities present so it be more than 0 or less than 0. So way the same steps to find y on its own e.g. y>3 all the numbers between 3 and 7 which is 4,5,6 and so you draw circle over 3 and 7 and you connect the lines however if the inequality symbol is less or equal to or more than equal to shade the circle to show the inequality if i tells you to draw it on a number line.
