Solving:

(3+4x)/(2) + (5-x)/(3) = (29)/(6)
Make the Least Common Multiple (2,3,6)

2,3,6\:|2

1,3,3\:|3

1,1,1\:|\underline{2*3=6}


Replace denominators and resolve:

(3+4x)/(2) + (5-x)/(3) = (29)/(6)

(3(3+4x))/(6) + (2(5-x))/(6) = (29)/(6)
Cancel the dominators

(3(3+4x))/(\diagup\!\!\!\!6) + (2(5-x))/(\diagup\!\!\!\!6) = (29)/(\diagup\!\!\!\!6)

3(3+4x) + 2(5-x) = 29

9 + 12x + 10 - 2x = 29

12x - 2x = 29 - 9 - 10

10x = 20 - 10

10x = 10

x = (10)/(10)

\boxed{\boxed{x = 1}}\end{array}}\qquad\quad\checkmark
