Answer:
[tex]-3\frac{1}{2}[/tex]
Step-by-step explanation:
Solve
[tex](x+y)[/tex]
For x=-1/2 and y=-3
substitute the value of x and the value of y in the expression above
[tex]x+y=(-\frac{1}{2})+(-3)[/tex]
Remember that
[tex](+1)(-1)=-1[/tex]
so
[tex]x+y=-\frac{1}{2}-3=\frac{-1-6}{2}=-\frac{7}{2}[/tex]
Convert to mixed number
[tex]-\frac{7}{2}=-\frac{6}{2}-\frac{1}{2}=-3\frac{1}{2}[/tex]
