#z=1#

To solve the equation, you need to isolate for #z#.

Thus, add #1/10# to both sides of the equation so that #z# is by itself on one side of the equation.

#z-1/10=9/10#

#z-1/10# #color(red)(+1/10)=9/10# #color(red)(+1/10)#

Solve.

#z+0=10/10#

Simplify.

#color(green)(|bar(ul(color(white)(a/a)z=1color(white)(a/a)|)))#
