4x-y=-12,4x+2y=0

Solution

4 x - y = - 12, 4 x + 2 y = 0

Solution

x = - 2, y = 4

Solution steps

[4 x - y = - 12 4 x + 2 y = 0]

Isolate

x

for

4 x - y = - 12 : x = \frac{- 12 + y}{4}

Substitute

x = \frac{- 12 + y}{4}

[4 \cdot \frac{- 12 + y}{4} + 2 y = 0]

Simplify

[- 12 + 3 y = 0]

Isolate

y

for

- 12 + 3 y = 0 : y = 4

For

x = \frac{- 12 + y}{4}

Substitute

y = 4

x = \frac{- 12 + 4}{4}

\frac{- 12 + 4}{4} = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = 4

Popular Examples

31(x+y)+2z=21,3x-(y+z)=6,5x+(x+y-z)=38

31 (x + y) + 2 z = 21, 3 x - (y + z) = 6, 5 x + (x + y - z) = 38

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

5x+2y=24,4x+3y=29

5 x + 2 y = 24, 4 x + 3 y = 29

y = 2 x - 1, 2 y - x = 7

-2x+2y=-4,3x+3y=-18

- 2 x + 2 y = - 4, 3 x + 3 y = - 18
