-2x-y=1,3x+4y=6

Solution

- 2 x - y = 1, 3 x + 4 y = 6

Solution

x = - 2, y = 3

Solution steps

[- 2 x - y = 1 3 x + 4 y = 6]

Isolate

x

for

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

Substitute

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

[3 (- \frac{1 + y}{2}) + 4 y = 6]

Simplify

[\frac{- 3 + 5 y}{2} = 6]

Isolate

y

for

\frac{- 3 + 5 y}{2} = 6 : y = 3

For

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

Substitute

y = 3

x = - \frac{1 + 3}{2}

- \frac{1 + 3}{2} = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = 3

- 2 x + 3 y = 14, 3 x - y = - 14

2x+4y=1,3x-5y=7

2 x + 4 y = 1, 3 x - 5 y = 7

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

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

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

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

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