Hi I'm studying forensics and i need help understanding how to work these out.I know how to rearrange formulae I'm just having trouble applying it to these type of equations. Help would be very much appreciated
The question states that I must combine the formulae so that I remove the letter in bold from the resulting equation.
6-2q=r and T=3qrs
here is what i've done so far
T=3qrs . i divide the r
t/r=3qs then I multiply the t
r=3qst this allows me to combine it with the first equation
the problem that i now have is how to arrange this formulae as the question stated.
to remove the q this is where I'm at a loss and my attempts have failed
if I be could showed the method it would be great.
i attempted it again, tho my algebra is somewhat rusty heres what I got:
T=3qrs , t/q=3rs, q=3rst. here im unsure if can move the q without the 3
tho if can move q freely it combined would be:
6-2x3rst=r ? though I not to sure as I don't know what to do with numbers
