Set up a linear system and solve it using elimination to determine the two numerators. (6 marks)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ = .
+ = .
First step to solve this system is to multiply each equation by 12 to rid off the denominators. You will get the system then
4x + 3y = 12*1712,
3x + 4y = 12*32.
Please complete it yourself.
