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

Solution

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

Solution

x = 2, y = - 1

Solution steps

[x + 3 y = - 1 2 x - y = 5]

Isolate

x

for

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

Substitute

x = - 1 - 3 y

[2 (- 1 - 3 y) - y = 5]

Simplify

[- 2 - 7 y = 5]

Isolate

y

for

- 2 - 7 y = 5 : y = - 1

For

x = - 1 - 3 y

Substitute

y = - 1

x = - 1 - 3 (- 1)

- 1 - 3 (- 1) = 2

x = 2

The solutions to the system of equations are:

x = 2, y = - 1

x-3y+2z=-3,5x+6y-z=13,4x-y+3z=8

x - 3 y + 2 z = - 3, 5 x + 6 y - z = 13, 4 x - y + 3 z = 8

5x-3y-z=1,x+4y-6z=-1,2x+3y+4z=9

5 x - 3 y - z = 1, x + 4 y - 6 z = - 1, 2 x + 3 y + 4 z = 9

x+3y=6,5x-2y=13

x + 3 y = 6, 5 x - 2 y = 13

49x+51y=499,51x+49y=501

49 x + 51 y = 499, 51 x + 49 y = 501

x + y = 4, x - y = 2
