5x-y=3,-2x+4y=-12

Solution

5 x - y = 3, - 2 x + 4 y = - 12

Solution

x = 0, y = - 3

Solution steps

[5 x - y = 3 - 2 x + 4 y = - 12]

Isolate

x

for

5 x - y = 3 : x = \frac{3 + y}{5}

Substitute

x = \frac{3 + y}{5}

[- 2 \cdot \frac{3 + y}{5} + 4 y = - 12]

Simplify

[\frac{- 6 + 18 y}{5} = - 12]

Isolate

y

for

\frac{- 6 + 18 y}{5} = - 12 : y = - 3

For

x = \frac{3 + y}{5}

Substitute

y = - 3

x = \frac{3 - 3}{5}

Simplify

x = 0

The solutions to the system of equations are:

x = 0, y = - 3

Popular Examples

2x-3y+7=5,x+2y+8=0

2 x - 3 y + 7 = 5, x + 2 y + 8 = 0

x+2y=-1,2x-3y=12

x + 2 y = - 1, 2 x - 3 y = 12

5x-6y-z=12,4x-3y+4z=15

5 x - 6 y - z = 12, 4 x - 3 y + 4 z = 15

3x-5y=4,9x-2y=7

3 x - 5 y = 4, 9 x - 2 y = 7

x - y = 3, 2 x + y = 12
