Question

X-1\2 +3\4=x-5\6+1\12 stie cineva?

Answer 1

Răspuns:

Explicație pas cu pas:

Inmultim ambele parti cu numitorul comun, 12. Dupa ce facem simplificari...$\frac{x-1}{2}+\frac{3}{4}=\frac{x-5}{6}+\frac{1}{12} ,~|*12,~\frac{12(x-1)}{2} +\frac{12*3}{4}=\frac{12(x-5)}{6}+\frac{12*1}{12} ,~ 6(x-1)+9= 2(x-5)+1,~6x-6+9=2x-10+1,~6x-2x=-10+1+6-9,~4x=-12,~x=(-12):4=-3.$
