I have a question

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

Is it C?

2 answers

clearly not C
3w+4-w=5w-2(w-2)
2w+4 = 5w-2w+4
2w+4 = 3w+4
w = 0

There is no solution if all the w's go away, leaving a false sentence like 2=4
No, the answer is D
