2x-5y=1,8-x+6y=-16

2 x - 5 y = 1, 8 - x + 6 y = - 16

x = - \frac{114}{7}, y = - \frac{47}{7}

Solution steps

[2 x - 5 y = 1 8 - x + 6 y = - 16]

Isolate

x

for

2 x - 5 y = 1 : x = \frac{1 + 5 y}{2}

Substitute

x = \frac{1 + 5 y}{2}

[8 - \frac{1 + 5 y}{2} + 6 y = - 16]

Simplify

[\frac{- 1 + 7 y}{2} + 8 = - 16]

Isolate

y

for

\frac{- 1 + 7 y}{2} + 8 = - 16 : y = - \frac{47}{7}

For

x = \frac{1 + 5 y}{2}

Substitute

y = - \frac{47}{7}

x = \frac{1 + 5 ( - \frac{47}{7} )}{2}

\frac{1 + 5 ( - \frac{47}{7} )}{2} = - \frac{114}{7}

x = - \frac{114}{7}

The solutions to the system of equations are:

x = - \frac{114}{7}, y = - \frac{47}{7}

x = - y, y = 0

f (x) = \frac{1}{3} x - 1, f (x) = 9

6 x + y = 31, 3 x + y = 16

33 x + 20 g (x, y) = 1, 2 x - 6 y = 1

2 x + 4 y = 10, 3 x + 6 y = 12
