Question

A) 4 x + 8,52 = 12; e) 7,2: (x-4,83) = 6:​

Answer 1

Ответ:

а)4х+8.52=12

4х=12-8.52

4х= 3.48

х= 3.48/4

х= 0.87

е)7.2 : (х-4.83) =6

36/5 : (х- 219/50)=6

36/5 : 50х-219/50 = 6

36/5 • 50/50х-219 = 6

36 • 10/50х-219 =6

360/50х-219=6

360= 6(50х-219)

60=50х-219

-50х = -279

х= 50/279
