The period of revolution of planet  A around the sun is 8 times that of B. The distance of A from the sun is how many times greater than that of B from the sun.

Let  and  A vector   is such that 

We can solve simultaneous equations as we feel easy for us. There are not any particular steps to be followed. We just have to solve the equation to find the values of the variables. We try to eliminate the variables using addition and subtraction to single out single variable.
