Question

решите уравнение а) 13/20 + x=7/12 +1/6 б) (11/12-x)-1/3=1/4 в) x- 1/8 = 5/8-1/7 г) 3/7-(x-2/5)=8/35 спасибо

Answer 1

а)х=9/12+13/20=45/60+39/60=84/60=1,4

б)11/12-х-1/3=1/4
х=11/12-1/3 - 1/4=11/12-4/12-3/12=1/3

в)х=5/8-1/7+1/8 =35/46-8/46+7/46=34/46=17/23

г)х=3/7+2/4-8/35=60/140+70/140-32/140=98/140
