5x+y=-19,7x-y=-16

5 x + y = - 19, 7 x - y = - 16

x = - \frac{35}{12}, y = - \frac{53}{12}

Solution steps

[5 x + y = - 19 7 x - y = - 16]

Isolate

x

for

5 x + y = - 19 : x = \frac{- 19 - y}{5}

Substitute

x = \frac{- 19 - y}{5}

[7 \cdot \frac{- 19 - y}{5} - y = - 16]

Simplify

[\frac{- 133 - 12 y}{5} = - 16]

Isolate

y

for

\frac{- 133 - 12 y}{5} = - 16 : y = - \frac{53}{12}

For

x = \frac{- 19 - y}{5}

Substitute

y = - \frac{53}{12}

x = \frac{- 19 - ( - \frac{53}{12} )}{5}

\frac{- 19 - ( - \frac{53}{12} )}{5} = - \frac{35}{12}

x = - \frac{35}{12}

The solutions to the system of equations are:

x = - \frac{35}{12}, y = - \frac{53}{12}

3 p - 5 q = - 3, 4 p - 5 p = 1

3 x + y = 2, 5 x - y = - 9

3 a + 2 b = 54, 5 a + 4 b = 92

2 x + 3 y = 7, 6 x - 5 y = 11

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