Due to seriouse dogmatic differences between the orthodox church and the western christian churches, the orthodox xhurch is not in communication with the roman catholic and protestant communities

If your question truly means "not in communication" -- then it is false.

If it is meant to say, "not in communion" -- then it is true.

Explanation:

"Communion" refers to a full alignment of churches together, where they share in ministry and sacraments together (such as shared communion in the Lord's Supper).  The Eastern Orthodox Church is not in full communion with Western churches, either Roman Catholic or Protestant.

"Communication" refers to dialogue and talking -- and Eastern Orthodox leaders do have dialogue and communication with leaders in both the Roman Catholic Church and Protestant churches.

The Orthodox Church and Roman Catholic Church have been involved in dialogues with one another since the time of Vatican II in the 1960s.  Orthodox observers were present at that Second Vatican Council.

Dialogue between the Orthodox Church and Protestant churches began in the late 19th century with efforts by the Church of England, and have continued in the 20th century to the present through the World Council of Churches.

1.3x - 2 - (3.3x + 5) = 2x + 1

1.3x - 2 - 3.3x - 5 = 2x + 1

-2x - 7 = 2x + 1

-7 = 4x + 1

-8 = 4x
