I am trying to solve a formula but i am completely stuck

The formula is zc.ρc = zw.ρw + zo.ρo + [zc-(zh + zw + zo)].ρm

Where ZH is height of himalaya, ZW is water depth, ZO is ocean crust And P is density (po=density of ocean crust etc)

The known numbers are(in km) ZH = 8, ZW = 5 and ZO = 7 i

And the mass is based on 1m2 (plus height of various variables)

What i have managed to push it down to, that i believe is correct is

zc.pc = 5.pw + 7.po + (zc-20).pm
