x+2y=-1,2x-3y=12

Solution

x + 2 y = - 1, 2 x - 3 y = 12

Solution

x = 3, y = - 2

Solution steps

[x + 2 y = - 1 2 x - 3 y = 12]

Isolate

x

for

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

Substitute

x = - 1 - 2 y

[2 (- 1 - 2 y) - 3 y = 12]

Simplify

[- 2 - 7 y = 12]

Isolate

y

for

- 2 - 7 y = 12 : y = - 2

For

x = - 1 - 2 y

Substitute

y = - 2

x = - 1 - 2 (- 2)

- 1 - 2 (- 2) = 3

x = 3

The solutions to the system of equations are:

x = 3, y = - 2

Popular Examples

5x-6y-z=12,4x-3y+4z=15

5 x - 6 y - z = 12, 4 x - 3 y + 4 z = 15

3x-5y=4,9x-2y=7

3 x - 5 y = 4, 9 x - 2 y = 7

x - y = 3, 2 x + y = 12

4x+6y=24,2x+3y=6

4 x + 6 y = 24, 2 x + 3 y = 6

x + 3 y = - 1, 2 x - y = 5
