8x+9y=-5,-8x-9y=5

8 x + 9 y = - 5, - 8 x - 9 y = 5

x = \frac{- 5 - 9 y}{8}

Solution steps

[8 x + 9 y = - 5 - 8 x - 9 y = 5]

Isolate

x

for

8 x + 9 y = - 5 : x = \frac{- 5 - 9 y}{8}

Substitute

x = \frac{- 5 - 9 y}{8}

[- 8 \cdot \frac{- 5 - 9 y}{8} - 9 y = 5]

Simplify

[5 = 5]

The solutions to the system of equations are:

x = \frac{- 5 - 9 y}{8}

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

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

8 x^{2} - 10 x - 63 = 2, y^{2} + 33 y - 17 = 0

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

x + y - z = 17, 0 x + z - y = 130 x
