5x+3y=-11,2x+4y=-10

5 x + 3 y = - 11, 2 x + 4 y = - 10

x = - 1, y = - 2

Solution steps

[5 x + 3 y = - 11 2 x + 4 y = - 10]

Isolate

x

for

5 x + 3 y = - 11 : x = \frac{- 11 - 3 y}{5}

Substitute

x = \frac{- 11 - 3 y}{5}

[2 \cdot \frac{- 11 - 3 y}{5} + 4 y = - 10]

Simplify

[\frac{- 22 + 14 y}{5} = - 10]

Isolate

y

for

\frac{- 22 + 14 y}{5} = - 10 : y = - 2

For

x = \frac{- 11 - 3 y}{5}

Substitute

y = - 2

x = \frac{- 11 - 3 ( - 2 )}{5}

\frac{- 11 - 3 ( - 2 )}{5} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = - 2

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

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

p (x) = 2, x + 1 x = \frac{1}{2}

x + y = 6, 2 x - 3 y = 27

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