Step-by-step explanation:

so the complimentary solution is

solving for particular solution we get

to find the values of constants a,b we put values in main equation and

as g(x)=sin x
so above equation yields us

so writing the solution

using IC's to get the values for 

solving for upper range

4x-18y=64
4x+y=-12
-19y=76
y=-4
4x+(-4)=-12
4x=-8
x=-2
W - 3w + 25w + w - 20
27w - 3w - 20
24w - 20
