-6-9x=-9x-4 is my answer 0 right
what happens when you add 9x to both sides?
the -9x on the left side goes away, so does the 9x on the right
leaving you with -6 = -4
what bout variable
what do you mean?
your answer has no vafriable
is -6 = -4 true? or false?
let me plug in for x and check one mine
what that means ? @jim_thompson5910
variable supposed to be on one side right
say you had something simple like x = x that's always true
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)
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
ok thx guys
