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

Solution

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

Solution

x = - 1, y = - 2

Solution steps

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

Isolate

x

for

2 x + y = - 4 : x = \frac{- 4 - y}{2}

Substitute

x = \frac{- 4 - y}{2}

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

Simplify

[\frac{- 20 - 11 y}{2} = 1]

Isolate

y

for

\frac{- 20 - 11 y}{2} = 1 : y = - 2

For

x = \frac{- 4 - y}{2}

Substitute

y = - 2

x = \frac{- 4 - ( - 2 )}{2}

\frac{- 4 - ( - 2 )}{2} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = - 2
