<span>During the week I always have to get up early for work so on Sunday I love to wake up late, usually around 9am and then get up 30 minutes later.</span><span>The first thing I do is switch on the coffee maker. No instant coffee for me today! On Sundays I always take the time to make some good coffee. While that's getting ready, I quickly throw onsome clothes and pick up a newspaper from the local shop.</span><span>With my coffee and paper, I spend the rest of the morning on the sofa. Sometimes I even turn offmy phone for a couple of hours so no one calls me.</span><span>Later in the day, I like to hang out with friends over lunch and catch up with their news and gossip.
</span><span>
</span><span>All in all, that's my idea of a good day!
ну вот так как то))

Ответ:
х1=9
х2=10^10-1
Объяснение:
ОДЗ: х+1>0, х>-1
логарифмическое квадратное уравнение, замена переменной:
D=81, t1=1, t2=10
обратная замена:
1). t1=1,
х+1=10
x=9. 9>-1, =>х =9 - корень уравнения
2). t2=10,
=> х=10^10-1 - корень уравнения
X - собственная скорость
тогда
3(х-3) + 2(х+3) = 37
3х-9+2х+6=37
5х=40
X=8
