!6. Rozwiaz rownania
f.y+3/2 -(1-y)=3,5
g. 1/5(y-3)-2/3(y-3/5)+1/3=2/5-1/3(2y-3)
h. 2y+4/4=1/2y+1
i. y-2/3+1/15-2y-5/3=8-4y/5
j. y-5/2+2y+3/5+1/3=y+7/15+y/2
Kreska / oznacza kreske ulamkowa !!!!!!!
W niektory podpunktach jest tak : y=7/15 tzn , y + 7 pietnastych !!!
Za rozwiazanieoczywiscie cenna nagroda !!!
Prosze szybko bo mam to na jutro !!!!!!!!
