x+y+1=0,x-y+1=0

Solution

x + y + 1 = 0, x - y + 1 = 0

Solution

x = - 1, y = 0

Solution steps

[x + y + 1 = 0 x - y + 1 = 0]

Isolate

x

for

x + y + 1 = 0 : x = - y - 1

Substitute

x = - y - 1

[- y - 1 - y + 1 = 0]

Simplify

[- 2 y = 0]

Isolate

y

for

- 2 y = 0 : y = 0

For

x = - y - 1

Substitute

y = 0

x = - 0 - 1

Simplify

x = - 1

The solutions to the system of equations are:

x = - 1, y = 0
