2x+4y=0,x+3y=7

Solution

2 x + 4 y = 0, x + 3 y = 7

Solution

x = - 14, y = 7

Solution steps

[2 x + 4 y = 0 x + 3 y = 7]

Isolate

x

for

2 x + 4 y = 0 : x = - 2 y

Substitute

x = - 2 y

[- 2 y + 3 y = 7]

Simplify

[y = 7]

For

x = - 2 y

Substitute

y = 7

x = - 2 \cdot 7

Simplify

x = - 14

The solutions to the system of equations are:

x = - 14, y = 7

2x+3y-z=15,17x+23y=189,2y-3z=-15

2 x + 3 y - z = 15, 17 x + 23 y = 189, 2 y - 3 z = - 15

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

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

3x+5y=11,2x-y=16

3 x + 5 y = 11, 2 x - y = 16

x-2y=4,x-2y=0,x+y=4,x+y=1

x - 2 y = 4, x - 2 y = 0, x + y = 4, x + y = 1

4x+y=3,4x+4y=16

4 x + y = 3, 4 x + 4 y = 16
