No, the distributive property means that you multiply the coefficient in front of the brackets with everything in the brackets. Or, a(b+c) is equal to ab+ac, not just ab+c or b+ac. Jordan multiplied only c by 6 and left the 48 as it is, which is wrong, because 6(c-48) would be equal to 6*c - 6*48, not just 6*c - 48. The correct answer would be 6(c-8) because 6*8=48.
