How do I make 'x' the subject for these? Can you please show all the steps and working out:
1) h = d - b/x
2) r - m/x = e^2
3) t^2 = b - n/x
4) 3M = M + N/P+x
5) m^2/x - n = -p
6) t = w - q/x
Thanks if you can help!
Hi sorry to bother you again, but I used the other one as an example and did #2. Can you check it?
r - m/x = e^2
-m/x = e^2 - r
m/x = r - e^2
m = x(r - e^2)
m/r - e^2 = x
And also I have two questions. Why did you multiply both sides by -1, and what is the purpose of swapping th order on the LHS? Thanks so much!
You wrote m/r- e^2= x and Pickslides wrote "be careful, though, use brackets m/(r- e^2)= x".
Which makes me ask- is your original problem r- m/x= e^2 (which is $\displaystyle r- \frac{m}{x}= e^2$) or (r- m)/x= e^2 (which is $\displaystyle \frac{r- m}{x}= e^2$)? Those are very different equations with very different solutions.
Similarly, was your first problem h= d- b/x ($\displaystyle h= d- \frac{b}{x}$) or h= (d- b)/x ($\displaystyle h= \frac{d- b}{x}$?
pickslides assumed it was the first in both of those.
