Question

(X-1/2)=9/16 resolver a equação

Answer 1

$\dfrac{x-1}{2} = \dfrac{9}{16} \to~~multiplique~~cruzado:\\\\ 16(x-1)=2.9\to\\\\ 16x-16=18\to\\\\16x = 18+16 \to\\\\ 16x = 34\to\\\\ x = \dfrac{34}{16} \to\\\\ \large\boxed{ x = \dfrac{17}{8}}$

Answer 2

x - 1            9
-------  =  --------
   2            16    (:2)

x - 1          9
-------  =  --------
   1            8

8.(x - 1) = 9
8x - 8 = 9
8x = 9 + 8
8x = 17

x = 17
      ----
       8
