Which equation has no solution?

a) 8 - (5v+3) = 5v-5

b) 3m-6=5m+7-m

c) 3w+4-w=5w-2 (w-2)

d) 7y+9=7y+6

Letter d has no solution because there is a positive 7y on both sides and when you will try to get y by itself they will cancel out because when you subtract 7y on both sides 7y will be subtracted and made 0

I think the answer would be b
