x-y=-1,2x-y=1

Solution

x - y = - 1, 2 x - y = 1

Solution

x = 2, y = 3

Solution steps

[x - y = - 1 2 x - y = 1]

Isolate

x

for

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

Substitute

x = - 1 + y

[2 (- 1 + y) - y = 1]

Simplify

[- 2 + y = 1]

Isolate

y

for

- 2 + y = 1 : y = 3

For

x = - 1 + y

Substitute

y = 3

x = - 1 + 3

Simplify

x = 2

The solutions to the system of equations are:

x = 2, y = 3
