Answer:

Below in bold.

Step-by-step explanation:

x + y = c

x/y = p/q

From the first equation y = c - x

So substituting in the second equation:

x / c -x = p/q

pc - px  = qx

qx + px = pc

x = pc /(p +q)

Now substitute for  x in the first equation:

pc /(p +q) + y = c

y = c -  pc/ (p + q)

y = pc + qc - pc)/ (p + q)

y = qc / (p+ q).
