Best ResponseYou've already chosen the best response.01) Distribute the 4.2 through the parentheses 2) Collect (combine) like terms  i.e.: add the coefficient of the terms with the variable, combine the constant terms (no variable) terms seperately. 1): \[4.2y  16.8 + (0.6y) = 13.2\] < I'd rather add a positive and negative then try to subtract, too easy to make a mistake. 2): \[3.6y = 13.2 + 16.8 > 3.6y = 30\] \[y = 30/3.6\]
