7x-15y=1,-x-6y=8

Solution

7 x - 15 y = 1, - x - 6 y = 8

Solution

x = - 2, y = - 1

Solution steps

[7 x - 15 y = 1 - x - 6 y = 8]

Isolate

x

for

7 x - 15 y = 1 : x = \frac{1 + 15 y}{7}

Substitute

x = \frac{1 + 15 y}{7}

[- \frac{1 + 15 y}{7} - 6 y = 8]

Simplify

[\frac{- 1 - 57 y}{7} = 8]

Isolate

y

for

\frac{- 1 - 57 y}{7} = 8 : y = - 1

For

x = \frac{1 + 15 y}{7}

Substitute

y = - 1

x = \frac{1 + 15 ( - 1 )}{7}

\frac{1 + 15 ( - 1 )}{7} = - 2

x = - 2

The solutions to the system of equations are:

x = - 2, y = - 1

3 x + 5 y = 8, 2 x - 4 y = - 2

-x+2y=4,2x-4y=3

- x + 2 y = 4, 2 x - 4 y = 3

x+2y=1,-3x+y=-10

x + 2 y = 1, - 3 x + y = - 10

-2x-y=1,3x+4y=6

- 2 x - y = 1, 3 x + 4 y = 6

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

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