Question

16x-10y=10
-8x-6y=6 i have to find x and y by elimination please show work !!

Answer 1

ok, so first you have to get either the x or the y to cancel each other out, so you multiply the second equation by 2 and get\[-16x-12y=12\]

then you combine them, and by doing so, eliminate x.
\[-22y=22\]
then you solve for y
divide by 22 and get \[y=-1\]
then you plug y back into the original equation (either one)
\[16x - (10\times-1) = 10\]
so you get
\[16x +10 = 10\]
solve for x (subtract 10)
\[16x=0\]
divide by 16\[x=0\]
so y=-1 and x=0

Answer 2

wow ur good i was wayyyyyyyy off track thanks :)

Answer 3

no problem
is this the method you are used to? i assumed elimination was the same as what we call combination

Answer 4

yes we are learning all three and elimination is the hardest i think
