Question

Which equation has no solution?

A. 7w+8-w=9w-2(w-4)
B. 3m-2=5m+3-m
C. 8-(3v+7)=3v-1
D. -4y+5=-4y-8

Answer 1

D have no solution!!!!

Answer 2

To check , whether the given equation has solution or not, lets start with first one

A.
`7w+8-w=9w-2(w-4)`

Open the parenthesis, and simplify

`image`

B.
`3m-2=5m+3-m\\`

`image`

C.
`8-(3v+7)=3v-1`

Take like terms together and simplify we get

`image`

D.
`-4y+5=-4y-8`

Take like terms together

`image`

Hence this equation has no solution.
