Step-by-step explanation:

To simplify the given expression, we need to distribute the coefficients and combine like terms.

Given expression: 3x(a+b) + 2y(5a+b) - 3z(3a+b)

Step 1: Distribute the coefficients for each term.

3x(a+b) = 3xa + 3xb

2y(5a+b) = 10ya + 2yb

-3z(3a+b) = -9za - 3zb

Step 2: Combine like terms.

3xa + 3xb + 10ya + 2yb - 9za - 3zb

Therefore, the simplified expression is:

3xa + 10ya - 9za + 3xb + 2yb - 3zb
