Question

X x (2 intregi si 2/3 x 1 intreg si 7/8 - 7/2 :14)=1/4

Answer 1

Răspuns:

X = 1 / 19

Explicație pas cu pas:

X x ( 2  2 / 3 x 1  7 / 8 - 7 / 2 : 14 ) = 1 / 4

X x ( 8 / 3 x 15 / 8 - 7 / 2 : 14 ) = 1 / 4

X x ( 5 - 7 / 2 : 14 ) = 1 / 4

X x ( 5 - 7 / 2 x 1 / 14 ) = 1 / 4

X x ( 5 - 1 / 4 ) = 1 / 4

X x ( 20 / 4 - 1 / 4 ) = 1 / 4

X x 19 / 4 = 1 / 4

19 / 4x = 1 / 4

X = 1 / 19
