2x-y=0,x-2y=6

Solution

2 x - y = 0, x - 2 y = 6

Solution

x = - 2, y = - 4

Solution steps

[2 x - y = 0 x - 2 y = 6]

Isolate

x

for

2 x - y = 0 : x = \frac{y}{2}

Substitute

x = \frac{y}{2}

[\frac{y}{2} - 2 y = 6]

Simplify

[- \frac{3 y}{2} = 6]

Isolate

y

for

- \frac{3 y}{2} = 6 : y = - 4

For

x = \frac{y}{2}

Substitute

y = - 4

x = \frac{- 4}{2}

\frac{- 4}{2} = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = - 4

Popular Examples

3x+2y=-25,-2x-y=10

3 x + 2 y = - 25, - 2 x - y = 10

x = 5, y = 2

x + y = 7, x - y = 1

3x+y=10,-4x+2y=2

3 x + y = 10, - 4 x + 2 y = 2

2036x+14y=-28,108x-42y=84

2036 x + 14 y = - 28, 108 x - 42 y = 84
