Let

a------------> first number

b------------> second number

we know that

a+b=-7--------> a=-7-b----------> equation 1

a-b=14--------> equation 2

I substitute 1  in 2

(-7-b)-b=14-------------> -7-b-b=14----------> -7-2b=14-------> 2b=-7-14

2b=-21---------> b=-10.5

a=-7-b-------> a=-7-(-10.5)-----> a=-7+10.5------> a=3.5

the answer is

the two numbers are

a=3.5

and

b=-10.5
