Question

0,5x + 1,(3) = 0,8(3) - 0,,75x vă rog​

Answer 1

0,5 = 5/10 = 1/2

1,(3) = (13-1)/9 = 12/9 = 4/3

0,8(3) = (83-8)/90 = 75/90 = 5/6

0,75 = 75/100 = 3/4

1/2x + 4/3 = 5/6 - 3/4x amplifici 1/2 cu 6, 4/3 cu 4, 5/6 cu 2 si 3/4 cu 3

6x + 16 = 10 - 9x

6x+9x = 10-16

15x = -6

x = -6/15 = -2/5
