1) 6/7 = 36/x6x = 7 * 366x = 252x = 252 / 6x = 42
2) 13/35 = x/4213 * 42 = 35x546 = 35xx = 546 / 35x ≈ 15.6
Ответ: x = 42 (для уравнения 1) и x ≈ 15.6 (для уравнения 2)
1) 6/7 = 36/x
6x = 7 * 36
6x = 252
x = 252 / 6
x = 42
2) 13/35 = x/42
13 * 42 = 35x
546 = 35x
x = 546 / 35
x ≈ 15.6
Ответ: x = 42 (для уравнения 1) и x ≈ 15.6 (для уравнения 2)
