Question

3целых3/10/(1/4x+5/12)-2целых3/5=7/10

Answer 1

(33/10*1/4х+33/10*5/12)- 2цел3/5=7/10

33/40х +33/24-13/5=710

33/40х=710-33/24+135

3340х=168240-330240+624240

33/40х=462/240

х=462/240*40/33

х=14/6=2 цел 2/6

Answer 2

33/40х+11/8 - 13/5=7/10

33/40х= 7/10 - 11/8+13/5

33/40х=77/40

х=77/40:33/40

х=7/3=2 целых 1/3
