W(22124+Z)=Mz+17, Z=........?
W(−4+z)=mz+17
z=........?
= -4w+wz=mz+17
= wz-mz=17+4w
- distribute the w to the terms inside the parenthesis
- add 4w to both sides to isloate the term with the z
- and subtract mz to both sides to transfer the mz (since it has a z too)
= z(w-m)=17+4w
the 2 terms in the left side has their gcf which is z so we factor it= z=(17+4w)/(-m+w)
