Question

solve each system by elimination
-1ox-y=-3
-5x+5y=15

Answer 1

-1x-y=-3
-5x+5y=15

So times first equation by -5:
5x+5y=15
Add both equations to elimeinate x:
10y=30
y=3.

Substitute to find x:
-x-y=-3
-x-3=-3
-x=0
x=0

Answer 2

is that a -10?

Answer 3

Its -10

Answer 4

no i hthink he accidentally typed 0

Answer 5

yeah its -10

Answer 6

aw man

Answer 7

i have to redo it now

Answer 8

-10x-y=-3
-5x+5y=15

So times second equation by -2:
10x-10y=-30
Add both equations to elimeinate x:
-11y=-33
y=3.

Substitute to find x:
-10x-y=-3
-10x-3=-3
-10x=0
x=0.

Oh its the same answers still!
