  1. Jane is not correct

    In 3a + b, there is one coefficients and there is one variable. That is perfectly fine but it can only be added if the variable is the same.It is also wrong as when you write "ab" it means a X b while you do not times a and b in this question but add them. So she is wrong

    In 2s + 4t its is the same case as the 2 variables are different so you cannot add them this jane is wrong again.
