Okay let’s go. Maybe I can do this
A) This one has no solutions because the answer of the equation is 0=-1 which isn't true.
b) 6t-3=3t+6 ==> 3t=9 ==> t=3 This means that this has one solution.
c) 6 (2m-3)-3m=2m-18+m ==> 12m-18=2m-18+m ==> 9m=0 ==> m=0 so this one has no solutions.
d) 10+3y-2=4y-y+8 ==> 8+3y=3y+8 ==> 0=0 ==> Infinitely many solutions.
~Hope I helped!~
K(2)+2(-2)=k
2k-4=k
+4 +4
2k=k+4
-k -k
K=4
