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

Solution

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

Solution

x = - 1, y = 0

Solution steps

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

Isolate

x

for

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

Substitute

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

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

Simplify

[- 3 y - 4 = - 4]

Isolate

y

for

- 3 y - 4 = - 4 : y = 0

For

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

Substitute

y = 0

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

\frac{- 2 - 0}{2} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = 0

2 x + y = 1, 2 x - 3 y = - 8

x+3y=10,4x+12y=16

x + 3 y = 10, 4 x + 12 y = 16

(4) 5 m - 3 n = 19, m^{6} n = - 7

x + y = 3, x + 6 y = 9

x + y = 7, 6 x + 5 y = 9
