x+y=-3,x-y=1

Solution

x + y = - 3, x - y = 1

Solution

x = - 1, y = - 2

Solution steps

[x + y = - 3 x - y = 1]

Isolate

x

for

x + y = - 3 : x = - 3 - y

Substitute

x = - 3 - y

[- 3 - y - y = 1]

Simplify

[- 3 - 2 y = 1]

Isolate

y

for

- 3 - 2 y = 1 : y = - 2

For

x = - 3 - y

Substitute

y = - 2

x = - 3 - (- 2)

Simplify

x = - 1

The solutions to the system of equations are:

x = - 1, y = - 2
