-5x+y=18,3x-y=-14

Solution

- 5 x + y = 18, 3 x - y = - 14

Solution

x = - 2, y = 8

Solution steps

[- 5 x + y = 18 3 x - y = - 14]

Isolate

x

for

- 5 x + y = 18 : x = - \frac{18 - y}{5}

Substitute

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

[3 (- \frac{18 - y}{5}) - y = - 14]

Simplify

[\frac{- 54 - 2 y}{5} = - 14]

Isolate

y

for

\frac{- 54 - 2 y}{5} = - 14 : y = 8

For

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

Substitute

y = 8

x = - \frac{18 - 8}{5}

- \frac{18 - 8}{5} = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = 8
