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]
