Номер 5 помогите пожалуйста 1)x×6=120 2)5×x=150 3)420-x=210
x÷6=120 x÷5=150. 26×x=78

Answer 1

x=120/6 x=150/5 x=420-210 x=120×6
x=20 x= 30 x=210 x=720


x=78/26
x=3

Answer 2

1) 120 : 6 = 60.
60 × 6 = 120.

2) 150 : 5 = 30
5 × 30 = 150

3) 420 - 210 = 210
420 - 210 = 210

120 × 6 = 720
720 : 6 = 120

150 × 5 = 750
750 : 5 = 150

78 : 26 = 3
26 × 3 = 78
