z=1

Explanation:

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)|)))
