Leon started to try to transform the expressions 6g + (g + 2) + 3 to determine if it is equivalent to the expression 6 + 7g. His work is shown below. 6g + (g + 2) + 3 (6g + g) + 2 + 3 associative property 7g + 2 + 3 combine like variable terms Are the expressions 6g + (g + 2) + 3 and 6 + 7g equivalent?
