What is x+y=-3 literal equation for y

Mr.geswein takes off 2 points for not showing work for each problem. james didn't show work on 6 problems.how many points did he lose?

In a certain pentagon, the interior angles are a,b,c,d,e where a,b,c,d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

Measure of angles 31 (x+4) (3x+9) me
