Question

1,6−15+(−2,52s)=14+1,6−7,52s
s= ?

Answer 1

$1,6−15+(−2,52s)=14+1,6−7,52s\\ 1.6 - 15 - 2.52s = 14 + 1.6 - 7.52s \\ - 2.52s + 7.52s = 14 + 1.6 - 1.6 + 15 \\ 5s = 29 \\ s = \frac{29}{5} \\ s=5,8$

Answer 2

Ответ:

$1,6-15+(-2,52s)=14+1,6-7,52s\\\\-13,4-2,52s=15,6-7,52s\\\\7,52s-2,52s=15,6+13,4\\\\5s=29\\\\s=5,8$
