Explanation:

Like terms are terms that are constants (no variables) here, and we identify the pair that are the matching constants from the implied original context (combining like constant terms). 37 and 12 are both constants that would be like terms to combine, while 5 is the separate constant in the other pairs.

Answer:

37 + 12 = 49
