Solving special systems
y=-2x-6
2x+y=5​

2

x

−

y

=

2

Subtract

2

x

from both sides.

−

y

=

−

2

x

+

2

Divide both sides by

−

1

. This will reverse the signs.

y

=

2

x

−

2

So both lines have the same slope of

2

x

.

graph{(y-2x-6)(2x-y-2)=0 [-16.83, 5.67, -19.26, -8.01]}

Step-by-step explanation:

a = 11 : 4

b = 38

c = 1 for every 6
