conservation of momentum... how do i find final velocity given initial mass 1, initial mass 2, and initial velocities of 1 and 2 ?

i tried using the equations m1v1 + m2v2 = m1v1' + m2v2' and 1/2 m1v1^2 etc (conservation of kinetic energy). i solved for v1' and plugged it into the conservation equation to solve for v2' and the algebra was just super hairy... am i even doing this right?
