x+2y+2=0,-2x+y-9=0

Solution

x + 2 y + 2 = 0, - 2 x + y - 9 = 0

Solution

x = - 4, y = 1

Solution steps

[x + 2 y + 2 = 0 - 2 x + y - 9 = 0]

Isolate

x

for

x + 2 y + 2 = 0 : x = - 2 y - 2

Substitute

x = - 2 y - 2

[- 2 (- 2 y - 2) + y - 9 = 0]

Simplify

[5 y - 5 = 0]

Isolate

y

for

5 y - 5 = 0 : y = 1

For

x = - 2 y - 2

Substitute

y = 1

x = - 2 \cdot 1 - 2

Simplify

x = - 4

The solutions to the system of equations are:

x = - 4, y = 1
