10x+18y=-11,16x-9y=-5

10 x + 18 y = - 11, 16 x - 9 y = - 5

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

Solution steps

[10 x + 18 y = - 11 16 x - 9 y = - 5]

Isolate

x

for

10 x + 18 y = - 11 : x = \frac{- 11 - 18 y}{10}

Substitute

x = \frac{- 11 - 18 y}{10}

[16 \cdot \frac{- 11 - 18 y}{10} - 9 y = - 5]

Simplify

[\frac{- 189 y - 88}{5} = - 5]

Isolate

y

for

\frac{- 189 y - 88}{5} = - 5 : y = - \frac{1}{3}

For

x = \frac{- 11 - 18 y}{10}

Substitute

y = - \frac{1}{3}

x = \frac{- 11 - 18 ( - \frac{1}{3} )}{10}

\frac{- 11 - 18 ( - \frac{1}{3} )}{10} = - \frac{1}{2}

x = - \frac{1}{2}

The solutions to the system of equations are:

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

x - y = 3, 6 x + y = 90

x + 3 y = 52, 5 x - 2 y = 4

2 x + 3 y = 3, 6 y - 6 x = 1

3 x + 2 y = 9, 5 x + 3 y = 14

4 x + 3 y = 7, 5 x - 4 y = 32
