Question

Find value of d in the equation ​

Answer 1

9/76

Explanation:

3(4d - 1) - (3d - 2) = 5/9d

open the brackets

3(4d - 1) = (12d -3) multiply by 3

12d - 3 - 3d + 2 = 5d

9

12d - 3d - 3 + 2 = 5d

9

9d - 1 = 5d

9

cross multiply

9(9d - 1) = 5d

81d - 9 = 5d

collect like terms

81d -5d = 9

76d = 9

d = 9/76
