B.
1

C.

D.
2

Answer 1

@ganeshie8 please help just this once

Answer 2

solve them and see ?

Answer 3

4x – 8y = 0
–3x + 8y = –7
----------------------

Answer 4

add them vertically, wat do u get ? :)

Answer 5

1x (+ or - idk) and 16y= -7

Answer 6

y's cancel out, and u wil get value of x

Answer 7

ok......

Answer 8

4x – 8y = 0
–3x + 8y = –7
----------------------
x + 0 = -7



x = -7

you will get some y value for this x, which is obvious.

So nothing special about the lines, they will just boringly cut in one point. So one solution

Answer 9

One solution x=-7, y=-7/2

Answer 10

Are you doing linear algebra?

Answer 11

yea @Moose23

Answer 12

Thanks again your a lifesaver @ganeshie8

Answer 13

np :) kind of u lol
