same thing as the last
do you not see how I did it?

anonymous · Answer

yes but still dont understand. sorry /:

zzr0ck3r · Answer

x = 2 + 5y
-2(2+5y) = 6 - 10y
-4 -10y = 6 - 10y
no solutions because -4 != 6

anonymous · Answer

was that wrong which i did???

anonymous · Answer

i dont know yet its a review packet i have to do @sradha

anonymous · Answer

what?

anonymous · Answer

let y = 0 for the first one what does x = 2

use -4 = 6 − 10y

anonymous · Answer

now what does y =?

anonymous · Answer

10y = 10

zzr0ck3r · Answer

no, there are no solutions. And that is not substitution

anonymous · Answer

ahhh oppsy

anonymous · Answer

well i tried

zzr0ck3r · Answer

I took the first equation and changed it around to be x = somehting( you could have made it y = something) then pluf that in for x (or y ) in the second equation. the algebra works out to be -4 = 6 thus there are no solutions

anonymous · Answer

theres no solution for it............

zzr0ck3r · Answer

you can always graph these and see where the intersect (these two dont)
