-7x-y=14,2y+3x=10

- 7 x - y = 14, 2 y + 3 x = 10

x = - \frac{38}{11}, y = \frac{112}{11}

Solution steps

[- 7 x - y = 14 2 y + 3 x = 10]

Isolate

x

for

- 7 x - y = 14 : x = - \frac{14 + y}{7}

Substitute

x = - \frac{14 + y}{7}

[2 y + 3 (- \frac{14 + y}{7}) = 10]

Simplify

[\frac{- 42 + 11 y}{7} = 10]

Isolate

y

for

\frac{- 42 + 11 y}{7} = 10 : y = \frac{112}{11}

For

x = - \frac{14 + y}{7}

Substitute

y = \frac{112}{11}

x = - \frac{14 + \frac{112}{11}}{7}

- \frac{14 + \frac{112}{11}}{7} = - \frac{38}{11}

x = - \frac{38}{11}

The solutions to the system of equations are:

x = - \frac{38}{11}, y = \frac{112}{11}

\frac{1}{x} + \frac{1}{y} = a, \frac{1}{x} - \frac{1}{y} = b

x + y = 4, x - y = 3

4 x + y = 17, 2 x + y = 11

y = - 2, x = 3

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