Question

Rezolva ecuatiile : 3 intreg x/3 -7/3 = 1 intreg 1/3; 2x + 12 intreg 0/7=26; 324 intreg 1/7 - 4intreg x/14 =156; 226/125 : ? =339/125.

Answer 1

a) /9+x/3=4/3, 9+x=4, x=4-9, x=-5.
b)2x+12 0/7=26, 2x+84/7=26, 2x+12=26, 2x=26-12, 2x=14, x=7.
c)  =2269/7-/56+x/14=156, 14×2269/7-14×/56+x/14=14×156,                           2×2269-(56+x)=2184,  4538-56-x=2184, 4482-x=2184, -x=2184-4482,                -x=-2298, x=2298.
