Can anyone help show me the process of solving the equations(adsbygoogle = window.adsbygoogle || []).push({});

(m1*v1)+(M2*V2)=(m1*v1')+(M2*V2')

(.5m1*v1^2)+(.5M2*V2^2)=(.5m1*v1')+(.5M2*V2')

to get the equations

------(m1+M2) (2M2v)

v1'= --------- v1 + ----- V2

------(m1+M2) (m1+M2)

-------(2m1) (M2-m1)

V2'= --------- v1 + ----- V2

------(m1+M2) (m1+M2)

i need the algebra used or at least how i should start i know you solve one and plug it into the other, but im not sure if i should start by factoring, expanding or what any help would be greatly appreciated
