Question

Укажите уравнение с наибольшим корнем :
1) X+60=120
2)Y-27=87
3)140-s=115
4)139+K=200

Answer 1

1)

$x + 60 = 120 \\ x = 120 - 60 \\ x = 60$

2)

$y - 27 = 87 \\ y = 87 + 27 \\ y = 114$

3)

$140 - s = 115 \\ - s = 115 - 140 \\ - s = - 25 \\ s = 25$

4)

$139 + k = 200 \\ k = 200 - 139 \\ k = 61$
