alignat: removing the gap between the aligned variable and its coefficient

For the second equation, how can I remove the space between the aligned dot{x}_1 and its coefficient without abusing extra ampersands?

documentclass[10pt,a4paper]{article}

usepackage{mathtools}

begin{document}

    begin{alignat*}{3}

    dot{v}_1 &= -frac{k}{M_1} x_1 - frac{d_1+d_2}{M_1} &&dot{x}_1 + frac{d_2}{M_1} &&dot{x}_2\

    %

    dot{v}_2 &= frac{d_2}{M_2} &&dot{x}_1 - frac{d_2}{M_2} &&dot{x}_2 + frac{f}{M_2}

    end{alignat*}

By its coefficient do you mean frac{d_2}{M_2}?

@Diaa the alignments are like tabular (it is the same tex halign command underneath) so it is a sequence of columns and x&& puts x in one column followed by a blank entry and &&x has a blank entry in one cell followed by x. the alignment is like begin{tabular}{rlrlrlrlrlrlrlrlrlr} so entries are left or right aligned depending which column they are in.

I propose one of these three variants – the last one with an extra pair of &:

    dot{v}_2 &= &frac{d_2}{M_2}&dot{x}_1 - frac{d_2}{M_2} &&dot{x}_2 + frac{f}{M_2}
