If 3 (d+1) = 4 (d-2), then what is the value of 5 (d-2) ?

Ans = > 45

Step-by-step explanation:

3 (d+1) = 4 (d-2)

Expanding the brackets we have:

3d + 3 = 4d - 8

our aim now is to solve for d

3d - 4d = - 8 - 3

-d = - 11

=> d = 11

we can now get 5 (d-2)

substituting d = 11

5 (11-2)

5 (9)

= 45
