Question

x/x+c=p/q make x the subject

Answer 1

X/x+c=p/q⇒X=p(x+c)/q
qX= p(x+c)
qX/p=x+c⇒qX-c=x
∴x=qX-c

Answer 2

Answer:

Step-by-step explanation:

Cross multiply to get

xq = xp + cp

Then transfer the ‘xp’ to the other side of the brackets

xq-xp = pc

Next your going to factorise

x(q-p) = pc

Then divide each side by ‘(q-p)’

Your answer will then be x = pc/(q-p)
