Respuesta :

The equation for z is z = (C - 0.41) / 0.26 + 1 .

What is the value of z?

In order to determine the value of z, take following steps given this equation: C = 0.41 + 0.26 (z - 1).

Subtract 0.41 from both sides of the equation:

C - 0.41 =  0.26 (z - 1).

Divide both sides of the equation by 0.26

(C - 0.41) / 0.26 = z - 1

Add one to both sides

z = (C - 0.41) / 0.26 + 1
