11x+15y=-23,10x+2y=20

11 x + 15 y = - 23, 10 x + 2 y = 20

x = \frac{173}{64}, y = - \frac{225}{64}

Solution steps

[11 x + 15 y = - 23 10 x + 2 y = 20]

Isolate

x

for

11 x + 15 y = - 23 : x = \frac{- 23 - 15 y}{11}

Substitute

x = \frac{- 23 - 15 y}{11}

[10 \cdot \frac{- 23 - 15 y}{11} + 2 y = 20]

Simplify

[\frac{- 230 - 128 y}{11} = 20]

Isolate

y

for

\frac{- 230 - 128 y}{11} = 20 : y = - \frac{225}{64}

For

x = \frac{- 23 - 15 y}{11}

Substitute

y = - \frac{225}{64}

x = \frac{- 23 - 15 ( - \frac{225}{64} )}{11}

\frac{- 23 - 15 ( - \frac{225}{64} )}{11} = \frac{173}{64}

x = \frac{173}{64}

The solutions to the system of equations are:

x = \frac{173}{64}, y = - \frac{225}{64}

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

3 x - 2 y = 12, 4 x + 3 y = 5, 2 x - y = 2

y = 2 (x + 10), 3 x + 2 y = 19

- 4 x + y = 20, 6 x - 9 y = 0

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