9/x+(10)/y =-11, 7/x-(15)/y =-4

\frac{9}{x} + \frac{10}{y} = - 11, \frac{7}{x} - \frac{15}{y} = - 4

(x = - 1, y = - 5)

Solution steps

[\frac{9}{x} + \frac{10}{y} = - 11 \frac{7}{x} - \frac{15}{y} = - 4]

Isolate

x

for

\frac{9}{x} + \frac{10}{y} = - 11 : x = - \frac{9 y}{10 + 11 y}; y \neq = - \frac{10}{11}

Plug the solutions

x = - \frac{9 y}{10 + 11 y}

into

\frac{7}{x} - \frac{15}{y} = - 4

For

\frac{7}{x} - \frac{15}{y} = - 4

, subsitute

x

with

- \frac{9 y}{10 + 11 y} : y = - 5

Plug the solutions

y = - 5

into

\frac{9}{x} + \frac{10}{y} = - 11

For

\frac{9}{x} + \frac{10}{y} = - 11

, subsitute

y

with

- 5 : x = - 1

Verify solutions by plugging them into the original equations

Therefore, the final solution for

\frac{9}{x} + \frac{10}{y} = - 11, \frac{7}{x} - \frac{15}{y} = - 4

(x = - 1, y = - 5)

4 x + 2 y = 9, 8 x + 2 y = 14

x = \frac{17}{11}, z = \frac{4}{121}

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

y + 1 = 2, (x - 1) ey - 1 = x + 1

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