Answx=3645

Step-by-step explanation:

3(x-1)+3(x+1)=21870

Taking 3 common,

3(x-1+x+1) = 21870

3(2x)       = 21870

6x           = 21870

x              = 21870/6

x              = 3645

Answer:

The answer will be 3645.

Step-by-step explanation:

                                   ⇒  3(x-1)+3(x+1)=21870;

                                   ⇒  3x - 3 + 3x + 3 =21870;

                                  ⇒   3x + 3x = 21870;        

                                  ⇒  6x = 21870;

                                  ⇒  x = 21870 / 6;

                                  ⇒  x = 3645

That's all.
