Question

How many solutions does the system have? y = -2x - 4 ly=3x +3

Answer 1

Step-by-step explanation:

y=-2x-4

y=3x+3

-----------

-2x-4=3x+3

-2x-3x-4=3

-5x-4=3

-5x=3+4

-5x=8

x=8/-5

y=-2(-8/5)-4

y=16/5-4

y=16/5-20/5=-4/5

Answer 2

Answer:

x=-8/5, y=-4/5. (-8/5, -4/5).

Step-by-step explanation:

y=-2x-4

y=3x+3

-----------

-2x-4=3x+3

-2x-3x-4=3

-5x-4=3

-5x=3+4

-5x=8

x=8/-5

y=-2(-8/5)-4

y=16/5-4

y=16/5-20/5=-4/5
