Question

Rezolvati q+ ecuatiile: (3/4+5/6) : 1,58(3)-4/5x=1/2

Answer 1

(3/4+5/6) : 1,58(3) - 4/5x = 1/2
(9/12 + 10/12) : (1583-158)/900 - 4/5x = 1/2
19/12 : 1425/900 - 4/5x = 1/2
19/12 : 19/12 - 4/5x = 1/2
19/12 x 12/19 - 4/5x = 1/2
1 - 4/5x = 1/2
4/5 x  = 1 - 1/2
4/5 x  = 1/2
x = 1/2 : 4/5
x = 1/2  x 5/4
x = 5/8
