Fantastic Linear equation

How to solve below question ???

A supermarket is selling three different fruits, i.e. apple, orange and pear. The price of an apple is RM *x*, the price of an orange is twice of an apple, and the price of a pear is RM *y*. Two different stalls, stall A and stall B get their supplies from this supermarket. Stall A bought 350 apples, 200 oranges and 300 pears and pays RM 680. Stall B bought 400 apples, 150 oranges and 250 pears and pays RM 530.

i) Based on the above information, form a system of linear equations.

ii) Write the above linear equations in the form of a matrix equation.
