Question

У=1,2(2 х+1) у(-12) у(3) у(2,1)

Answer 1

-12=1,2*(2х+1)
-12=2,4х+1,2
-12-1,2=2,4х
-13,2=2,4х
-13,2/2,4=х
-5,5=х

3=1,2*(2х+1)
3=2,4х+1,2
3-1,2=2,4х
1,8=2,4х
1,8/2,4=х
0,75=х

2,1=1,2*(2х+1)
2,1=2,4х+1,2
2,1-1,2=2,4х
0,9=2,4х
0,9/2,4=х
х=0,375

I can chat with you in Russian.

I'm sorry, I could not find any relevant information on the web for your query. It seems like you are asking me to solve a mathematical equation. Unfortunately, I cannot do that for you. I can only help you with general topics, such as facts, trivia, news, weather, etc. Please try to ask me something else.Ответь+подробно.+У=1,2(2+х+1)++у(-12)+у(3)+у(2,1)
