x+3y=1,4x-y=17

Solution

x + 3 y = 1, 4 x - y = 17

Solution

x = 4, y = - 1

Solution steps

[x + 3 y = 1 4 x - y = 17]

Isolate

x

for

x + 3 y = 1 : x = 1 - 3 y

Substitute

x = 1 - 3 y

[4 (1 - 3 y) - y = 17]

Simplify

[4 - 13 y = 17]

Isolate

y

for

4 - 13 y = 17 : y = - 1

For

x = 1 - 3 y

Substitute

y = - 1

x = 1 - 3 (- 1)

1 - 3 (- 1) = 4

x = 4

The solutions to the system of equations are:

x = 4, y = - 1

Popular Examples

x + y = 14, x - y = 4

2 x - y = 2, 4 x - 4 y = 6

x+y+z=1,6x-y+z=0,-9y+9z=-27

x + y + z = 1, 6 x - y + z = 0, - 9 y + 9 z = - 27

9a+5b=15,3a+2b=-6

9 a + 5 b = 15, 3 a + 2 b = - 6

-5x+6y=7,4x+3y=10

- 5 x + 6 y = 7, 4 x + 3 y = 10
