what happens when you add 9x to both sides?

OpenStudy (anonymous):
0

jimthompson5910 (jim_thompson5910):
the -9x on the left side goes away, so does the 9x on the right

jimthompson5910 (jim_thompson5910):
leaving you with -6 = -4

variable supposed to be on one side right

OpenStudy (anonymous):
Yes

jimthompson5910 (jim_thompson5910):
say you had something simple like x = x
that's always true

jimthompson5910 (jim_thompson5910):
x = x+1 is false because there is no way you can have a number equal the next number after that same number (eg: there's no way 5 could equal 6)

OpenStudy (anonymous):
But if you want to know the answer, just plug in the number you got (Ex: For you, 0) for the variables

x = x+1
x-x = x+1-x ... Subtract x from both sides.
0 = 1 ... this is false, so there are no solutions
