HELP. WILL MARK BRAINLIEST

1. Which Equation Has No Solution:
5w+4-w=9w-2(w-2)
3x-5=3x+8-x
7z+6=-7z-5
4y+5=4y-6

Answer 1

4y+5=4y-6 doesn't have a solution because you need to subtract 4y from both sides so you do 4y+5-4y=4y-6-4y so 5= -6 and then you subtract 5 from both sides which is 5-5=-6-5 and 0=-11.

Answer 2

Answer:

4y+5=4y-6

Step-by-step explanation:

It has no solution, because if

4y+5=4y-6

then

4y -4y = -6-5

So,

0 = -11 and we have no solution! the variable y was cancelled and we couln't find the solution.
