Question

-v + 5 + 6v = 1 + 5v + 3

Answer 1

Combine your like terms: 5v + 5 = 5v +4
subtract the 5v and 4 from each side:  0 = 1

because 0 $\neq$ 1, there is no solution

Answer 2

-v + 5 + 6v = 1 + 5v + 3
=> 5v + 5 = 1 + 5v + 3
=> 5v + 5 = 5v + 4 
=> 5=4
=>5 not equal to 4 
=> since 5 is not equal to 4 , there is no solution ..

hope it helps !!!
