x+2y=1,-3x+y=-10

Solution

x + 2 y = 1, - 3 x + y = - 10

Solution

x = 3, y = - 1

Solution steps

[x + 2 y = 1 - 3 x + y = - 10]

Isolate

x

for

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

Substitute

x = 1 - 2 y

[- 3 (1 - 2 y) + y = - 10]

Simplify

[- 3 + 7 y = - 10]

Isolate

y

for

- 3 + 7 y = - 10 : y = - 1

For

x = 1 - 2 y

Substitute

y = - 1

x = 1 - 2 (- 1)

1 - 2 (- 1) = 3

x = 3

The solutions to the system of equations are:

x = 3, y = - 1

Popular Examples

-2x-y=1,3x+4y=6

- 2 x - y = 1, 3 x + 4 y = 6

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

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

2x+4y=1,3x-5y=7

2 x + 4 y = 1, 3 x - 5 y = 7

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

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

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