First: the homogeneous solutions: the characteristic equation is4r^2 - 4r - 3 = 0which has roots r = 3/2, -1/2 hence the homogeneous solution isy = c1.exp(-x/2) + c2.exp(3x/2)
next you need the general form for the guess for yp and that isyp = A1cos(2x) + A2sin(2x)
Now substitute that into the equation and solve for A1, A2.

Answer:
60 lbs large and 25 lbs small box
Step-by-step explanation:
50 large and 50 small boxes = 50 * 85 = 4250
5150-4250 =900 lbs weigh of 15 big boxes,
1 big box= 900 divide 15 = 60 lbs
85-60= 25 lbs = 1 small box
