4x+2y=-60,-2x-6y=12

4 x + 2 y = - 60, - 2 x - 6 y = 12

x = - \frac{84}{5}, y = \frac{18}{5}

Solution steps

[4 x + 2 y = - 60 - 2 x - 6 y = 12]

Isolate

x

for

4 x + 2 y = - 60 : x = - \frac{y + 30}{2}

Substitute

x = - \frac{y + 30}{2}

[- 2 (- \frac{y + 30}{2}) - 6 y = 12]

Simplify

[- 5 y + 30 = 12]

Isolate

y

for

- 5 y + 30 = 12 : y = \frac{18}{5}

For

x = - \frac{y + 30}{2}

Substitute

y = \frac{18}{5}

x = - \frac{\frac{18}{5} + 30}{2}

- \frac{\frac{18}{5} + 30}{2} = - \frac{84}{5}

x = - \frac{84}{5}

The solutions to the system of equations are:

x = - \frac{84}{5}, y = \frac{18}{5}

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

\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
