two spheres of mass 2kg and 3kg travelling in opposite direction with velocities 8m/s and 6m/s collide. is the collision is perfectly inelastic, then the final velocity?

m1=2kg. m2=3kg
u1=8m/s. u2=(-6m/s).
(traveling opposite direction)
v1=x. v2=x
v1=v2
by change of momentum
m1u1+m2u2= m1v1+m2v2
2(8)+3(-6)=2(x)+3(x)
19-18=2x+3x
1=5x
x=5
therefore final velocity= 5m/s
u1=8m/s. u2=(-6m/s).
