Question

How many solutions does this system have?

–3x + 6y = 10
–3x + 6y = –4

A.none
B.one***
C.infinite
D.two

Answer 1

Now how can I be 10 years old and 4 years before birth at once :(

Those are two parallel lines, they never cross.

THERE IS NO SOLUTION !!!!

Answer 2

You can tell the lines are parallel if you solve each equation for y. The number in front of the x is the slope as in y =mx+b

6y =3x + 10 divide by 6 to get m=1/2

second equation 6y = 3x -4 m = 1/2

or you could graph both equations and see that they are parallel.
