Looks good so far
Now put the x's on the same side.
Factor out x.
Finish him off.
(New here, hope I'm posting in the right forum...)
Hello! I am working on a set of 30 problems to do with transposing equations. I have been doing well up until now, but I have hit this at question 28:
y = (a + x) / (5 - bx) rearranged for x
I know that the answer should be:
x = (5y - a) / (1 + by)
My working so far is:
y(5 - bx) = a + x
5y - ybx = a + x
...and now I get stuck. I can't seem to isolate x. I see that both the question and answer are equal but I don't see how they got there (also confused where the constant "1" came from). Any help with this would be greatly appreciated!
