x+4y=-25,-10x-5y=5

Solution

x + 4 y = - 25, - 10 x - 5 y = 5

Solution

x = 3, y = - 7

Solution steps

[x + 4 y = - 25 - 10 x - 5 y = 5]

Isolate

x

for

x + 4 y = - 25 : x = - 25 - 4 y

Substitute

x = - 25 - 4 y

[- 10 (- 25 - 4 y) - 5 y = 5]

Simplify

[250 + 35 y = 5]

Isolate

y

for

250 + 35 y = 5 : y = - 7

For

x = - 25 - 4 y

Substitute

y = - 7

x = - 25 - 4 (- 7)

- 25 - 4 (- 7) = 3

x = 3

The solutions to the system of equations are:

x = 3, y = - 7
