Answer 1

Step-by-step explanation:

Let us assume the numbers as x and y,

It says sum of x and y gives -1

we can say,

x + y = - 1

Now it says one of them is -5/7

let us suppose x = -5/7

Now he is asking to find y so simply substitute x = -5/7

x + y = -1

-5/7 + y = -1

y = -1 + 5/7

y = (-7+5)/5

y = -2/5
