i think maybe it is either a or b, not c for sure
what do you get when you distribute
u get a? i dunno i am confused on this
forget about the options right now
6(2x-3) is equivalent to what?
ok do the same for the right side
oh u get 9x-15 correct?
we now have 12x - 18 = 9x - 15
are you able to isolate x?
tell me what you get
oh oh oh so the answer is a
yes so there is exactly one solution (which is x = 1)
it's only an identity if both sides are the same example `x = x` or `2x+3 = 2x+3` identities are equations that have infinitely many solutions
oh ok my bad
i know for a fact c is not correct so the real answer must be b
why isn't C correct?
because it is neither contradiction or identity and we both know that a is not correct
and i know that a or b must be it, but offcourse, a is wrong so the answer is b
why is it a contradiction? a contradiction is something that has no solutions at all
example of a contradiction `2x + 3 = 2x + 5`
i though contradiction means it has one solution
contradiction is something that has no solutions
oops my bad
i guess the answer is c then...
` 2x + 3 = 2x + 5` simplifies to `3 = 5` which is always false there are no x values that make the equation true. So there are no solutions
OH I GET It!!!
another way to think of it: identity means left side = right side no matter what x is (it works for all x values) contradiction means left side never equals right side (no x value works)
