3x-1/2 - 2(4+3x)/13 = 2
distribute
3x -1/2 -8/13 -6x/13 =2
combine like terms
3x-6x/13 -1/2 -8/13 =2
multiply by 26 to get rid of the fractions (2*13)
26*(3x-6x/13 -1/2 -8/13) =2*26
78x - 12x -13 -16 = 52
66x -29 =52
add 29 to each side
66x =81
x = 81/66
divide top and bottom by 3
x=27/22
x = 1 5/22
