and please tell me how to solve it❤

Answer 1

Explanation:

This is true. -1 =-1

Answer 2

True

Explanation:

`(x - y )/(x + y)=-1` ---------------(I)

Cross multiply

x - y = -1*(x + y)

x - y = (-1)*x + y * (-1)

x - y = -x - y

x - y + x = - y

2x - y = -y

2x = -y + y

2x = 0

x = 0

Plugin x = 0 in (I)

`(0-y)/(0+ y) = -1\\\\(-y)/(y)=-1\\\\-1 = -1`

So , true
