Question 1061825
{{{-7q+12r=3q-4r}}}


That is an equation in two variables, and only in two variables.  No mention, showing of any "g" is found.  You cans simplify the equation,...{{{-10q=-16r}}}
{{{10q=16r}}}
{{{5q=8r}}}
but you still have no information telling you anything exact about the function g(q).


The information given is not enough to answer the question of what is the function g(q).
