12x-5y=-2,0y=x+4

12 x - 5 y = - 2, 0 y = x + 4

x = - 4, y = - \frac{46}{5}

Solution steps

[12 x - 5 y = - 2 0 \cdot y = x + 4]

Isolate

x

for

12 x - 5 y = - 2 : x = \frac{- 2 + 5 y}{12}

Substitute

x = \frac{- 2 + 5 y}{12}

[0 \cdot y = \frac{- 2 + 5 y}{12} + 4]

Simplify

[0 = \frac{- 2 + 5 y}{12} + 4]

Isolate

y

for

0 = \frac{- 2 + 5 y}{12} + 4 : y = - \frac{46}{5}

For

x = \frac{- 2 + 5 y}{12}

Substitute

y = - \frac{46}{5}

x = \frac{- 2 + 5 ( - \frac{46}{5} )}{12}

\frac{- 2 + 5 ( - \frac{46}{5} )}{12} = - 4

x = - 4

The solutions to the system of equations are:

x = - 4, y = - \frac{46}{5}

- x + y = 6, 3 x - 2 y = - 12

1 b = 14, m = 1

2 x - y = 1, x + y = 11

3 x + 4 y = 16, 4 x + 2 y = 10

2 x + y = 2 x y, x + 2 y = 4 x y
