Answer 1

`d=11.3125`

Explanation:

Given

`(-4(-8.625+2d))/(-8) +3=10`

Lets solve for
`d.`

Start on the left side with the fraction.

Factor -4 out of -8.

`(-4(-8.625+2d))/(-4(2)) +3=10`

Cancel the common factor of -4.

`(-8.625+2d)/(2) +3=10`

Subtract 3 from both sides.

`(-8.625+2d)/(2) =7`

Multiply both sides by 2.

`(-8.625+2d)/(2) *2=14`

Cancel the common factor of 2.

`-8.625+2d=14`

`2d-8.625=14`

Add 8.625 to both sides.

`2d=22.625`

Divide both sides by 2.

`d=11.3125`
