x-y=-1,-2x-y=0

Solution

x - y = - 1, - 2 x - y = 0

Solution

x = - \frac{1}{3}, y = \frac{2}{3}

Solution steps

[x - y = - 1 - 2 x - y = 0]

Isolate

x

for

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

Substitute

x = - 1 + y

[- 2 (- 1 + y) - y = 0]

Simplify

[2 - 3 y = 0]

Isolate

y

for

2 - 3 y = 0 : y = \frac{2}{3}

For

x = - 1 + y

Substitute

y = \frac{2}{3}

x = - 1 + \frac{2}{3}

- 1 + \frac{2}{3} = - \frac{1}{3}

x = - \frac{1}{3}

The solutions to the system of equations are:

x = - \frac{1}{3}, y = \frac{2}{3}

Popular Examples

5x-3y=14,3x-5y=2

5 x - 3 y = 14, 3 x - 5 y = 2

2 x - y = 1, y - 5 x = 2

3x+2y=1,2x-y+1=0

3 x + 2 y = 1, 2 x - y + 1 = 0

3x+2y=27,5x_{3}y=25

3 x + 2 y = 27, 5 x_{3} y = 25

2 x + y = 7, x + 3 y = 1
