Question

aflatil pe x,unde (2x-1/2):6=1/2​

Answer 1

Răspuns:

2x:6-1/2:6=1/2

2x•1/6-1/2•1/6=1/2

x/3-1/12=1/2

x/3=1/2+1/12 (amplific pe 1/2 cu 6)

x/3=6/12+1/12

x/3=7/12

x•12=7•3

x=21/12 (simplific cu 3)

x=7/4

Explicație pas cu pas:

Proba:

(2•7/4-1/2):6= 1/2

(7/2-1/2):6=1/2

6/2:6=1/2

6/2•1/6= 1/2

1/2=1/2
