Linear resolution is an essential technique in commutative algebra to study invariants such as betti numbers, projective dimension, and regularity. These invariants play a considerable role in learning the topologies of different algebraic structures. Here, we study a construction known as linearization. Linearization is a way of constructing an ideal from a monomial ideal I in a single degree but in a larger polynomial ring. The new ideal Lin(I) has linear resolution and linear quotients. Furthermore, we discuss another technique, equification, to generalize the linearization to all the monomial ideals. Equification converts a non-equigenerated monomial ideal I to an equigenerated monomial ideal Ieq in a polynomial ring with one more variable. Moreover, we see the connection between the syzygies of I and I eq and investigate their betti numbers. Our aim is to introduce a class of ideals, for which the syzygy of Ieq is derived from the syzygy of I.
