Question

Solve by elimination.
5x + y = 5
9x - 4y = -20

Answer 1

Ok, i don't really know If Im doing this the right way but here I go:

5x + y = 5
9x - 4y = -20

5x + y = 5 => x4
9x - 4y = -20

20x + 4y = 20
9x - 4y = -20

29x = 0

20x/29 = 0/29

x = 0

LOL I think this might be Wrong.

@mohammad.arqum You tell...

Answer 2

ok...its oke

Answer 3

I guess it's right then! :D

Answer 4

hmmm well the problem is multiple choice. The choices are:
A. (15/29, -220/29)
B. (-15/29, 220/29)
C. (0,-5)
D. (0,5)

Answer 5

ok when x=0 then put the value of x in the first equation...
5x+y=5
5(0) + y = 5
0 + y = 5
y=5
therefore the solution is (0,5)
option D

Answer 6

The answer is "D"
