solve the given system of differential equations by systematic elimination.

Solution. Our aim is to find the general solution using systematic elimination. Step. 1. Given set of differential equation defined as where …………………… (1)…………………….. (2)Step 2. Multiply D in equation 2 and 1 in equation 1 then subtract (1) by (2) , then we get…………………… (1)…………………….. (2)After subtracting we get ……………………….(3)Step 3. Now to find C.F and P.I of equation 3.For C.F put Then let us consider D = m and y = 1 we get……………………. (4)For P.I ……………………………… (5)Therefore ……….. (6)Now similarly we need to find Step 4. Multiply D in equation 1 and 1 in equation 2 then add(1) by (2) , then we get…………………… (1)…………………….. (2)After adding we get ……………………….(7)
