Question

solve the equation, solve for d:
2d+1/6=6(1/3d+1)

Answer 1

2d + 1/6 = 2d+ 6
0d = 6 - 1/6

This is not a valid solvable question

Answer 2

2d+1/6= 6(1/3d +1)
            =multiply                                            

2d+1/6 =6/3d + 6
    -1/6             -1/6

d*(2d)  = (2/d + 5.8) *d

2d^2 = 7.8
/2        /2

√d^2 =√3.9

d =1.9
