10 and 3/4 plus 3 and 3/4 = 14 and 1/2 or 14.5
14 quarters plus 7 quarters = 21 quarters= 5 and a quarter (1 quarter is 1 fourth)
1 whole = 4 fourths 4 wholes = 16 fourths 4 wholes minus 2 fourths = 16 fourths minus 2 fourths = (16 - 2) fourths = 14 fourths 14 fourths = 3 wholes plus 2 fourths, or 3 wholes plus 1 tooth.

33/12 + 14/12 = 47/12 or 3 and 11/12
13/14
it equals 28
12 + 16/12 + 9/12 + 1/12 = 12 and 26/12 = 14 and 1/6
16
14 + 14 = 28
-14
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
