A new iterative scheme is proposed which approximates a common solution of split equality fixed point problems involving \(\eta -\)demimetric mappings, finite family of \(\gamma \)-inverse strongly monotone mappings, finite family of relatively quasi-nonexpansive mappings and finite family of system of generalized mixed equilibrium problems in real Banach spaces which are 2-uniformly convex and uniformly smooth. Our theorems extend and complement several existing results in this area of research.
