Question

уравнение 9,54- 4,74:(0,3x+0,49x)=8,94

Answer 1

9.54-4.74:(0.3х+0.49х)=8.94

9.54-4.74:0.79х=8.94

9.54-8.94=4.74:0.79х

0.6=4.74:0.79х

0.79х=4.74:0.6

0.79х=7.9

х=7.9:0.79

х=10.

Answer 2

9,54 -4,74:(0,3х+0,49х)=8,94

9,54-4,74:0,79= 8.94

9,54 -8,94 =4,74 :0,79

4,74:0,79х=0,6

0.79х= 4,74 :0.6 

0,79х= 7,9

х=10
