Right even Marx himself talks about how price will often deviate from value in the first chapters of Capital vol. 1. He didn't go into great detail about the LTV because at the time, pretty much everyone (including the bourgeois political economists) took the LTV for granted.
And pretty much as a rule, the prices are almost never equal to the value. But Marx did hold three aggregate equalities, namely that total values equal total prices, total surplus value equals total profit, and total price rate of profit equals total value rate of profit.
