Question

Graph the two equations to solve the system. What is the solution?
1/2 x - 2y = 4 and 4y - x = -8
Answer

(-2, 0)

no solution

(3, 4)

infinitely many solutions

Answer 1

do u know matrices?

Answer 2

Answer 3

ummm no? what is that?

Answer 4

@charlieberzak
Is first equation like this
1/(2x-2y) =4 ?? or is like (1/2x)-2y=4 ??

Answer 5

i think its
0.5x-2y=4
-x+4y=-8

Answer 6

from this we can see that line 1 is -2 lots of the second equation. hence the lines are parallel and co-incident. therefore there are infintely many solution.

Answer 7

-2x0.5=-1 -2x-2=4 -2x4=-8
