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

Solution

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

Solution

x = - 1, y = 1

Solution steps

[x + 2 y = 1 - 3 x - y = 2]

Isolate

x

for

x + 2 y = 1 : x = 1 - 2 y

Substitute

x = 1 - 2 y

[- 3 (1 - 2 y) - y = 2]

Simplify

[- 3 + 5 y = 2]

Isolate

y

for

- 3 + 5 y = 2 : y = 1

For

x = 1 - 2 y

Substitute

y = 1

x = 1 - 2 \cdot 1

Simplify

x = - 1

The solutions to the system of equations are:

x = - 1, y = 1

Popular Examples

5 x - y = 6, x + 3 y = 10

x+6y=27,7x-3y=9

x + 6 y = 27, 7 x - 3 y = 9

3x-5y=20,6x-10y=40

3 x - 5 y = 20, 6 x - 10 y = 40

3x-4y=-6,2x+4y=16

3 x - 4 y = - 6, 2 x + 4 y = 16

4 x + y = 7, 2 x - y = 5
