Question

найдите х по данным на рисунке ​

Answer 1

Решаем как простое уравнение:

1) 3/5х + 80 = 125

3/5х = 125 - 80 = 45

х = 45 / 3/5 = 45 * 5 / 3 = 75

2) 360 / 2 = 180

3/4х + 117 = 180

3/4х = 180 - 117 = 63

х = 63 / 3/4 = 63 / 3 * 4 = 8_

3) 2/3х + 40 = 84

2/3х = 84 - 40 = 44

х = 44 / 2/3 = 44 * 3 / 2 = 66
