Помогите пожалуйста с заданием...
1) 18,08-X=10,7; 2) X+2,39=12,5; 3) 16,68+y=26,5; 4) 3,55+X=5,6.

Answer 1

1)

$18.08 - x = 10.7 \ - x = 10.7 - 18.08 \ - x = - 7.38 \ x = 7.38$

2)

$x + 2.39 = 12.5 \ x = 12.5 - 2.39 \ x = 10.11$

3)

$16.68 + y = 26.5 \ y = 26.5 - 16.68 \ y = 9.82$

4)

$3.55 + x = 5.6 \ x = 5.6 - 3.55 \ x = 2.05$
