Let x = number of long sleeve shirts
Let y = number of short sleeve shirts
x + y = 200
x/2 + y/3 = 80
Now solve this pair of simultaneous equations to find x and y.
If you do width times length you will get 30. Good luck
To find the x intercept just substitute your y value for 0 then solve for x.
So you get 0= x+3 and then you get x=-3 which is at (-3,0).
