6x+4y=8,-x-4y=12

Solution

6 x + 4 y = 8, - x - 4 y = 12

Solution

x = 4, y = - 4

Solution steps

[6 x + 4 y = 8 - x - 4 y = 12]

Isolate

x

for

6 x + 4 y = 8 : x = \frac{2 ( - y + 2 )}{3}

Substitute

x = \frac{2 ( - y + 2 )}{3}

[- \frac{2 ( - y + 2 )}{3} - 4 y = 12]

Simplify

[\frac{- 10 y - 4}{3} = 12]

Isolate

y

for

\frac{- 10 y - 4}{3} = 12 : y = - 4

For

x = \frac{2 ( - y + 2 )}{3}

Substitute

y = - 4

x = \frac{2 ( - ( - 4 ) + 2 )}{3}

\frac{2 ( - ( - 4 ) + 2 )}{3} = 4

x = 4

The solutions to the system of equations are:

x = 4, y = - 4
