We simplify the equation to the form, which is simple to understand
q+2/5=2q-11/7

Simplifying:
q + 0.4=2q-11/7

Simplifying:
q + 0.4=2q-1.57142857143

We move all terms containing q to the left and all other terms to the right.
+1q-2q=-1.57142857143-0.4

We simplify left and right side of the equation.
-1q=-1.97142857143

We divide both sides of the equation by -1 to get q.
q=1.97142857143
