Question

Please help with this one, I don't know how to solve it.

Answer 1

`(4d+2)/(4)=2d+1`

First, divide the left side:

`d+(1)/(2)=2d+1`

Move the "d" terms to the left side of the equation:

`d-2d=1-(1)/(2)`
`-d=(1)/(2)`

Multiply both sides of the equation by -1.

`-d(-1)=(1)/(2)(-1)`
`d=-(1)/(2)`

Correct option: a
