-10x-9y=29,-6x+18y=-6

- 10 x - 9 y = 29, - 6 x + 18 y = - 6

x = - 2, y = - 1

Solution steps

[- 10 x - 9 y = 29 - 6 x + 18 y = - 6]

Isolate

x

for

- 10 x - 9 y = 29 : x = - \frac{29 + 9 y}{10}

Substitute

x = - \frac{29 + 9 y}{10}

[- 6 (- \frac{29 + 9 y}{10}) + 18 y = - 6]

Simplify

[\frac{117 y + 87}{5} = - 6]

Isolate

y

for

\frac{117 y + 87}{5} = - 6 : y = - 1

For

x = - \frac{29 + 9 y}{10}

Substitute

y = - 1

x = - \frac{29 + 9 ( - 1 )}{10}

- \frac{29 + 9 ( - 1 )}{10} = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = - 1

7 x + 5 y - 3 z = 16, 3 x - 5 y + 2 z = - 8, 5 x + 3 y - 7 z = 0

9 x + 6 y = 8, 4 x - 2 y = 4

x + y = g (x, y), 8 x - y = 0

8 x + 4 y = - 4, 10 x - 4 y = 4

y = \frac{1}{( x ^{2} )}, x = 2, x = 3
