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

Solution

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

Solution

x = - 1, y = 1

Solution steps

[3 x + 2 y = - 1 5 x + y = - 4]

Isolate

x

for

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

Substitute

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

[5 \cdot \frac{- 1 - 2 y}{3} + y = - 4]

Simplify

[\frac{- 5 - 7 y}{3} = - 4]

Isolate

y

for

\frac{- 5 - 7 y}{3} = - 4 : y = 1

For

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

Substitute

y = 1

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

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

x = - 1

The solutions to the system of equations are:

x = - 1, y = 1

Popular Examples

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

3 x - y = 5, 2 x - 3 y = 8

5(x-2)+2y=-5,3(x+y)-8=2(y-2)

5 (x - 2) + 2 y = - 5, 3 (x + y) - 8 = 2 (y - 2)

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

2x-4y=36,4x+2y=82

2 x - 4 y = 36, 4 x + 2 y = 82
