x/2+12=2-x/3+3x
naj oczywiscie :)
+ 12 = 2 - + 3x || mnożymy razy 6
3x + 72 = 12 - 2x + 18x
5x + 60 = 18x
13x = 60
x = 4
3x/6+72/6=12/6-2x/6+18x/6 /*6
3x+72=12-2x+18x
3x+2x-18x=12-72
-13x=-60 /:(-13)
x=60/13= 4 i 8/13
spr.60/13*1/2+12=2-60/13*1/3+3*60/13
30/13+12=2-20/13+180/13
30/13+156/13=26/13-20/13+180/13
186/13=186/13
