Rearranging the equation so q is the independent variable is; q = -1.6r
We are given the expression;
-7q + 12r = 3q - 4r
Since we want to make q the subject, let us rearrange the equation with variables having q on the left and others on the right side to get;
-7q - 3q = -4r - 12r
-10q = -16r
q = 16r/10
q = -1.6r
