Concept:Multiply every term inside a bracket by the number outside it, then collect like terms. A minus sign outside a bracket changes the sign of every term inside.Solution:$2(3a + 1) = 6a + 2$$-3(4a - 3) = -12a + 9$$6a + 2 - 12a + 9 = -6a + 11 = 11 - 6a$Key point: $-3 \times (-3) = +9$, not $-9$.Answer:Option B ($11 - 6a$)
