Question

Solve (x+y) if x=-1/2 and y=-3

Answer 1

`-3(1)/(2)`

Explanation:

Solve

`(x+y)`

For x=-1/2 and y=-3

substitute the value of x and the value of y in the expression above

`x+y=(-(1)/(2))+(-3)`

Remember that

`(+1)(-1)=-1`

so

`x+y=-(1)/(2)-3=(-1-6)/(2)=-(7)/(2)`

Convert to mixed number

`-(7)/(2)=-(6)/(2)-(1)/(2)=-3(1)/(2)`
