Question

Solve the equation -16(d+1) = -20.

Answer 1

d = 1/4

Explanation:

- 16 (d + 1) = - 20

- 16d - 16 = - 20

- 16d = -20 + 16

- 16d = - 4

d =
`(-4)/(-16)`

d =
`(1)/(4)`

Answer 2

`d=(1)/(4)`

Explanation:

`-16(d+1)=-20` (given)

`-16d-16=-20` (expand the brackets)

`-16d=-4`

`d=(1)/(4)`

Hope this helps :)
