a measures for comparing two values and counting the result in Power BI

Question

How can I write a measure to count the number of userID for which sum(x1) is equal to count(order_id), in Power BI?

For example, my data table is:

userID	x1	order_id
141	1	719
172	0	616
172	0	189
172	0	2211
172	0	317
1103	1	98
1103	1	213
1103	1	15
2524	0	4902
2524	1	3620

and I use table visual of power bi for this, to explain my mean:

userID	sum(x1)	count(order_id)
141	1	1
172	0	4
1103	3	3
2524	1	2

Note that the userID column is one of the columns in my data table, and calculating sum(x1) and count(order_id) in this sample is by Power BI default features.

The result for this sample should be 2. I need a measure that returns 2.

Answer 1

Measure1 = 
VAR _base1 =
    SUMMARIZE ( 'Table 1', 'Table 1'[userID] )
VAR _base2 =
    ALLEXCEPT ( 'Table 1', 'Table 1'[userID] )
VAR _ct =
    ADDCOLUMNS ( _base1, "X", CALCULATE ( COUNT ( 'Table 1'[order_id] ), _base2 ) )
VAR _sum =
    ADDCOLUMNS ( _base1, "X", CALCULATE ( SUM ( 'Table 1'[x1] ), _base2 ) )
VAR _nt =
    NATURALINNERJOIN ( _sum, _ct )
RETURN
    COUNTROWS ( _nt )

or

Measure4 =
VAR _1 =
    COUNTX (
        VALUES ( 'Table 1'[userID] ),
        VAR _base =
            ALLEXCEPT ( 'Table 1', 'Table 1'[userID] )
        VAR _1 =
            CALCULATE ( SUM ( 'Table 1'[x1] ), _base )
        VAR _2 =
            CALCULATE ( COUNTROWS ( 'Table 1' ), _base )
        VAR _3 =
            IF ( _1 = _2, 1 )
        RETURN
            _3
    )
RETURN
    _1
