Answer

Here is the solution for the equation:
3(p + q) = p

First, distribute the 3 on the left side:
3p + 3q = p

Next, subtract p from both sides to isolate the variable terms:
3q = -2p

Finally, divide both sides by 3 to solve for q:
q = (-2p)/3

Therefore, the solution for the equation 3(p + q) = p is q = (-2p)/3.
