first distribute the % on the right
29+2d=5d-10
take the -10 to the left and 2d to the right
39=3d
13=d

29 + 2d = 5d-10
add 10 to both sides
39 + 2d = 5d
minus 2d from both sides
39 = 3d
divide each side by 3 to get what d =
d = 13

29 + 2d = 5(d - 2)
29 + 2d = 5d - 10 - expand right hand side
39=3d - group common terms on either side
d=13 - divide by 3 on each side
