Leaders of the Republican-controlled North Carolina legislature on Tuesday announced details of a tentative budget agreement, including a 7 percent pay raise for teachers in public schools, that could end a monthlong stalemate that has exposed a breach between Republican conservatives and moderates in the state.

Legislative leaders announced some details of the $21.3 billion spending plan in an afternoon news conference in Raleigh, the capital. Most notably, they highlighted the $282 million earmarked for teacher salary increases. Phil Berger, the president pro tem of the Senate, said the money would raise North Carolina’s average pay for public teachers to 32nd in the nation from 46th.

Mr. Berger and Speaker Thom Tillis of the House, in a joint news release, said it amounted to “the largest teacher pay raise in state history without raising taxes.”

But a number of analysts said Tuesday that they had a less-than-clear picture of where the state would get the $282 million. The answer is likely to be found in the text of the compromise bill, which was expected to be released on Wednesday.
