1 - 2k + 5k <_ -4 + 3k

vova2212 [387]

Answer:

No solution.

Step-by-step explanation:

1-2k+5k<-4+3k Combine like terms on each side wherever you can.

1+3k<-4+3k Subtract -3k on both sides (it's less confusing when you get

-3k -3k rid of the variable first).

1<-4 1 is not less than or equal to -4, so there is no solution.

I hope this helped you out!! Have a great day (*^3^)╭
