2x+y=-1,0x-3y=2

2 x + y = - 1, 0 x - 3 y = 2

x = - \frac{1}{6}, y = - \frac{2}{3}

Solution steps

[2 x + y = - 1 0 \cdot x - 3 y = 2]

Isolate

x

for

2 x + y = - 1 : x = \frac{- 1 - y}{2}

Substitute

x = \frac{- 1 - y}{2}

[0 \cdot \frac{- 1 - y}{2} - 3 y = 2]

Simplify

[- 3 y = 2]

Isolate

y

for

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

For

x = \frac{- 1 - y}{2}

Substitute

y = - \frac{2}{3}

x = \frac{- 1 - ( - \frac{2}{3} )}{2}

\frac{- 1 - ( - \frac{2}{3} )}{2} = - \frac{1}{6}

x = - \frac{1}{6}

The solutions to the system of equations are:

x = - \frac{1}{6}, y = - \frac{2}{3}

3 x - 4 y = 20, x - 12 y = - 20

2 x - y = 90, x - 3 y = - 40

2 x - 3 y = 30, 3 x - 4 y - 5 = 0

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

8 x + 5 y = 9, 3 x + 2 y = 4
