12x+8y=-92,-2.5y+x=-33

12 x + 8 y = - 92, - 2.5 y + x = - 33

x = - 13, y = 8

Solution steps

[12 x + 8 y = - 92 - 2.5 y + x = - 33]

Isolate

x

for

12 x + 8 y = - 92 : x = - \frac{2 y + 23}{3}

Substitute

x = - \frac{2 y + 23}{3}

[- 2.5 y - \frac{2 y + 23}{3} = - 33]

Isolate

y

for

- 2.5 y - \frac{2 y + 23}{3} = - 33 : y = 8

For

x = - \frac{2 y + 23}{3}

Substitute

y = 8

x = - \frac{2 \cdot 8 + 23}{3}

- \frac{2 \cdot 8 + 23}{3} = - 13

x = - 13

The solutions to the system of equations are:

x = - 13, y = 8

83 x + 71 y = 35, 71 x + 83 y = 472

x + y = 7, x + 3 y = 15

x - y = 5, 2 x + 3 x = 0

7 x + y = 19, 4 x - y = 3

2 x + 5 y = 5, - 3 x + 7 y = 36
