is the second eqn correct?mean where is the equality sign?
What i mean by flip is in the equation x - y = 4 4y - x = 14 I flip the x - y = 4 to x = 4 + y
Sorry equation is supposed to be 7z - 3x = 18 Z - 5x = 1
look z has got coefficient 1, so its easy to handle with that
you flip which ever one you want; make a choice and stick with it
Because my Algebra instructor flipped the first one
So it is a matter of choice, it doesn't matter which one you flip? You will get the same answer out of both?
it doesnt matter which variable you start with, or which equation .... just do what you think is easiest for you to solve with ...
that will lead to fractional value, a bot hard..nothing wrong with it anyways
She came up with 7z = 18 + 3x z + 18 + 3x / 7 / = fraction
and that is completely usable ..... but does it have to be done that way? no
and then it was 2(18 + 3x / 7) - 5x = 1
since z=z=z=z.... it doesnt matter how you 'solve' for z; its gonna retain the same value thruout the process
To avoid fractions (which I hate) I would flip the 2z - 5x = 1
an orange ball is still an orange ball regardless of whether its in the bathtub or the dogpen...
z = z ; so go with whats easiest for you to play with lol
Are you saying either way I will get an equation?
you might end up using fractions; dunno ..... i havent solved it ;)
I am going to try ad solve it! (The other way)
fractions can be cleared tho; just multiply it all by the bottom number
Now that is something I actually know. lol
Thanks for the help once again!
I have 7z - 3x = 18 2z = 1 + 5x And now I dk what to do
